Defining 'Migrant' in the UK: Navigating Complexities for UK Visa and Immigration

Under United Kingdom law, there is no single statutory definition of a 'migrant'; instead, legal rights and obligations depend strictly on whether an individual is subject to immigration control under the Immigration Act 1971. A person's status is defined by their specific leave to enter or remain, their right of abode, or their settled status, rather than general demographic labels. Understanding where an individual sits within this legal framework dictates their rights to live, work, study, access public funds, and ultimately settle permanently in the UK.

The Legal and Operational Framework: Defining Immigration Status in the UK

While public discourse, economic reporting, and demographic research use the term 'migrant' broadly, the Home Office and UK immigration tribunals operate strictly on legal categories. An individual is either subject to immigration control or exempt from it. How a person is categorised governs every interaction with the state, including border entry, employment eligibility, tenancy checks, higher education tuition fees, and access to the National Health Service (NHS).

The Immigration Act 1971 and the Right of Abode

The foundational legislation governing UK border and immigration control is the Immigration Act 1971. Under Section 1 and Section 2 of this Act, the law divides individuals into two fundamental groups:

1. Persons with the Right of Abode: British citizens and certain Commonwealth citizens who held the right of abode before 1 January 1983 are entirely free from UK immigration control. They have the absolute right to enter, live in, exit, and re-enter the UK without requiring permission from the Home Office.
2. Persons Subject to Immigration Control: Anyone who does not hold the right of abode requires permission (leave to enter or leave to remain) to be lawfully in the United Kingdom, unless they qualify for a specific statutory exemption (such as accredited diplomats or members of visiting armed forces).

Irish citizens occupy a unique statutory position under Section 1(3) and Section 3ZA of the Immigration Act 1971, preserved through the Common Travel Area (CTA) arrangements. Irish nationals generally do not require leave to enter or remain in the UK and are treated as settled from the date they take up residence, provided they are not subject to a deportation order or exclusion direction.

Dissecting Demographic Categories vs Legal Status

Confusion frequently arises because different governmental and international bodies use the word 'migrant' to mean distinct concepts. When assessing legal exposure or visa eligibility, applicants and employers must separate demographic descriptions from legal status:

• Foreign-Born Individuals: This demographic category, used by the Office for National Statistics (ONS) and the UK Census, encompasses anyone born outside the UK. It includes millions of British citizens who acquired nationality by descent, naturalisation, or registration, as well as foreign nationals. A foreign-born British citizen is not subject to immigration control.
• Foreign Nationals: This category covers individuals who do not hold British citizenship. A foreign national may be temporarily present on a visa, settled under Indefinite Leave to Remain (ILR), holding Pre-Settled or Settled Status under the EU Settlement Scheme (EUSS), or residing without lawful status. Their legal rights depend entirely on their current immigration permission.
• Long-Term International Migrants (LTIM): Based on the United Nations statistical definition, this refers to anyone who changes their country of usual residence for a period of at least 12 months. This metric includes British citizens returning after living abroad, international students undertaking multi-year degrees, skilled workers, and refugees.

For practical immigration purposes, caseworkers at UK Visas and Immigration (UKVI) do not assess whether an applicant is a 'migrant'. They assess whether the applicant satisfies the specific requirements of the Immigration Rules for a defined category of leave.

The Core Tiers of Immigration Status

Every non-British and non-Irish national residing in or travelling to the UK falls into a defined legal tier. Determining which tier applies is the necessary first step in any immigration assessment.

[British / Irish Citizens / Right of Abode] -> Exempt from Immigration Control
                     |
[Indefinite Leave to Remain / Settled Status] -> Settled (No Time Limit, No Work Restrictions)
                     |
[Limited Leave to Enter / Remain] -> Lawful Temporary Permission (Conditions Apply)
                     |
[Section 3C Leave] -> Statutory Extension of Previous Permission During Processing
                     |
[Without Leave / Overstayer] -> Unlawful Presence (Subject to Enforcement and Penalties)

Tier 1: Exempt from Immigration Control

This group holds an unfettered right to live, work, study, and access public funds in the UK. It consists of:

• British citizens (by birth, descent, naturalisation, or registration);
• Commonwealth citizens with statutory Right of Abode (evidenced by a Certificate of Entitlement in a valid passport);
• Irish citizens exercising Common Travel Area rights; and
• Diplomats and members of designated international organisations exempt under Section 8 of the Immigration Act 1971.

Tier 2: Settled Status and Indefinite Leave

Settled persons are free from immigration time restrictions. They can engage in any employment or business activity and access public funds (subject to standard statutory eligibility criteria). Categories include:

• Indefinite Leave to Enter (ILE) or Indefinite Leave to Remain (ILR): Granted under the Immigration Rules or through historical legislation;
• Settled Status under the EU Settlement Scheme (Appendix EU): Granted to EEA and Swiss citizens (and their eligible family members) who established continuous residence in the UK before 31 December 2020 and completed a qualifying period of five years;
• Permanent Residence: Historical status under EU free movement, which required conversion to EUSS Settled Status following the end of the transition period.

Settled status can lapse if the holder remains outside the UK for continuous periods (two years for standard ILR, four years for Swiss citizens under the EUSS, and five years for EEA citizens with EUSS Settled Status).

Tier 3: Limited Leave to Enter or Remain

Limited leave provides lawful temporary presence in the UK subject to specific statutory conditions. These conditions are stamped on entry visas, detailed on Biometric Residence Permits (BRPs), or stored within UKVI digital status accounts (eVisa). Standard conditions include:

• A fixed expiry date;
• Employment restrictions (e.g., restricted to a specific licensed sponsor, restricted weekly hours for students, or prohibition on working as a professional sportsperson);
• Study restrictions (e.g., Academic Technology Approval Scheme (ATAS) requirements);
• The 'No Recourse to Public Funds' (NRPF) condition, barring access to designated welfare benefits and local authority housing assistance.

Tier 4: Section 3C Statutory Leave

Under Section 3C of the Immigration Act 1971, if an individual makes an in-time, valid application for further leave to remain before their existing limited leave expires, their existing leave and all associated conditions (such as the right to work) are automatically extended by law. This extension lasts while the application remains pending, during any statutory administrative review period, or while an in-country appeal is active. Section 3C leave prevents the applicant from becoming an overstayer.

Tier 5: Persons Without Lawful Leave

An individual whose leave has expired without a valid pending in-time application, whose leave has been curtailed, or who entered the UK without permission is an overstayer or unlawful entrant. Under the Immigration Act 1971 and the Immigration Act 2014, unlawful presence triggers significant legal consequences:

• Criminal liability under Section 24 of the Immigration Act 1971;
• Immediate revocation of the right to work (creating civil penalty liability for employers);
• Disqualification from renting residential property in England under the 'Right to Rent' scheme;
• Freezing or closure of UK bank accounts;
• Revocation of UK driving licences;
• Mandatory re-entry bans ranging from 12 months to 10 years under Part 9 of the Immigration Rules if the individual leaves the UK at public expense or after overstaying.

Comparison of Major UK Immigration Routes

The following table outlines the structural, financial, and operational requirements across primary UK visa and immigration categories. Fees and thresholds reflect published Home Office schedules.

Step-by-Step Process: Determining Legal Status and Selecting an Immigration Route

Navigating UK immigration requires a structured, sequential assessment. Each step contains critical decision points where an adverse finding halts the process or requires alternative legal remedies.

Step 1: Identity & Nationality Verification
   -> Right of Abode / Irish Citizen? -> Yes: No Visa Required
   -> No: Proceed to Step 2

Step 2: Current Status & Lawful Presence Assessment
   -> Overstayer / Breach? -> Assess Exception (Para 39E) or Human Rights / Voluntary Departure
   -> Valid Leave / Out of Country? -> Proceed to Step 3

Step 3: Route Selection & Eligibility Analysis
   -> Skilled Work / Family / Study / Business -> Check Mandatory Rule Criteria
   -> Criteria Met? -> Proceed to Step 4

Step 4: Financial & Language Verification
   -> Appendix FM-SE / Appendix Finance / Appendix English Language
   -> Compliant? -> Proceed to Step 5

Step 5: Suitability & Part 9 Screening
   -> Criminality / False Representation / Previous Breaches?
   -> Clear? -> Proceed to Step 6

Step 6: Submission, Biometrics, and Decision
   -> Application lodged -> Biometrics enrolled -> Decision received

Step 1: Nationality, Right of Abode, and CTA Verification

The initial assessment examines whether an individual requires a visa at all:

• Decision Point 1.1: Does the individual hold British citizenship by birth, descent, registration, or naturalisation? If yes, they require a British passport or certificate of entitlement. No visa is permitted or required.
• Decision Point 1.2: Is the individual an Irish citizen? If yes, CTA rights apply. They can enter, reside, and work freely without an application, unless subject to exclusion.
• Decision Point 1.3: Is the individual an eligible non-British Commonwealth citizen who possessed the Right of Abode prior to 1 January 1983? If yes, an application for a Certificate of Entitlement on a valid foreign passport is required.
• Outcome if not met: The individual is subject to immigration control and must hold valid leave to enter or remain.

Step 2: Assessment of Current Immigration Status and Lawful Presence

Before lodging any application, an applicant's current standing within the UK must be established:

• Decision Point 2.1: Is the applicant currently inside the UK? If outside the UK, entry clearance rules apply.
• Decision Point 2.2: If inside the UK, is the applicant's current leave valid? If yes, check the expiry date to calculate the deadline for an in-time variation application to trigger Section 3C leave.
• Decision Point 2.3: Has the applicant's leave already expired? If yes, examine whether the application can be submitted within the 14-day grace period under Paragraph 39E of the Immigration Rules. Paragraph 39E applies only if there was a good reason beyond the control of the applicant or their representative, which must be evidenced in writing with the application.
• Outcome if not met: If the applicant has overstayed beyond 14 days or cannot establish exceptional reasons under Paragraph 39E, any in-country application under standard economic or study routes will be rejected as invalid or refused on eligibility grounds. The individual must either leave the UK to apply for entry clearance or seek specialist advice regarding human rights claims under Article 8 of the European Convention on Human Rights (ECHR).

Step 3: Determining the Route and Sponsorship Requirements

The applicant must align their circumstances with a specific category under the Immigration Rules:

• Decision Point 3.1 (Sponsored Work): Does the applicant have a valid Certificate of Sponsorship (CoS) assigned by a Home Office licensed sponsor? Does the job code fall under the eligible Standard Occupational Classification (SOC) 2020 list? Does the salary meet or exceed both the general threshold and the specific occupation going rate?
• Decision Point 3.2 (Family): Does the applicant have a qualifying relationship with a British citizen, settled person, or person with refugee status? Is the relationship genuine and subsisting, and is any previous marriage or civil partnership legally dissolved?
• Decision Point 3.3 (Study): Does the applicant hold a Confirmation of Acceptance for Studies (CAS) from an approved Student sponsor for an eligible, full-time academic course?
• Outcome if not met: If sponsorship or qualifying relationship criteria are absent, the application will be refused without substantive consideration of other factors.

Step 4: Financial, Maintenance, and English Language Requirements

Applicants must satisfy strict objective criteria regarding self-sufficiency and language proficiency:

• Decision Point 4.1 (Financial Capability): Can the applicant demonstrate maintenance funds held for 28 consecutive days in an account meeting Appendix Finance rules, or has an A-rated sponsor certified maintenance on the CoS? Under Appendix FM (Family), does the sponsor earn at least £29,000 gross per annum, or hold sufficient cash savings calculated under the formula £16,000 + (2.5 × shortfall)?
• Decision Point 4.2 (English Language): Does the applicant hold a qualifying nationality from a majority English-speaking country, have a degree taught in English verified by Ecctis, or have a Secure English Language Test (SELT) certificate from an approved provider (e.g., IELTS SELT Consortium, Pearson, Trinity College London, PSI Services) at the required Common European Framework of Reference (CEFR) level (A1, A2, B1, or B2 depending on the route)?
• Outcome if not met: Failure to provide compliant financial evidence in the exact format required by Appendix FM-SE or Appendix Finance triggers mandatory refusal. Caseworkers possess limited discretion under Evidential Flexibility rules and are not required to request missing baseline evidence.

Step 5: Suitability, Criminality, and General Grounds for Refusal

Every application is screened against Part 9 of the Immigration Rules (Suitability and General Grounds for Refusal):

• Decision Point 5.1: Has the applicant received a custodial sentence of 12 months or more? (Mandatory refusal across almost all routes).
• Decision Point 5.2: Has the applicant engaged in deception, false representation, or non-disclosure of material facts in the current or any previous immigration application? (Triggers mandatory refusal under Paragraph 9.7.1 and a potential 10-year ban).
• Decision Point 5.3: Does the applicant owe a debt of at least £500 to the NHS, or are there outstanding litigation debts owed to the Home Office?
• Outcome if not met: If mandatory suitability grounds apply, the visa must be refused regardless of whether the applicant meets all points, salary, or relationship criteria.

Step 6: Application Submission, Biometrics, and Decision Outcomes

The formal process proceeds through distinct administrative phases:

• Online Application and Fee Payment: The applicant submits the digital form and pays the visa fee and the Immigration Health Surcharge (IHS).
• Biometric Enrolment: The applicant attends a visa application centre (VFS Global or TLScontact overseas; UKVCAS / Sopra Steria in the UK) or uses the 'UK Immigration: ID Check' mobile application to scan their biometric passport and upload facial imagery.
• Caseworker Assessment: The Home Office reviews the documentation against the relevant Appendices.
• Decision:
  • Grant: The applicant receives entry clearance (a vignette in their passport or digital permission) or permission to remain (eVisa / updated digital status).
  • Refusal: The applicant receives a formal Refusal Notice setting out the legal grounds and specifying whether a right of Administrative Review (under Appendix AR) or a right of Appeal to the First-tier Tribunal (Immigration and Asylum Chamber) exists.

Evidence and Documentation: What Caseworkers Evaluate

Home Office caseworkers do not assess claims on general credibility alone; they verify documentary trails against technical criteria. Applications succeed or fail based on strict documentary compliance.

Identity & Nationality       Sponsorship & Endorsement       Financial Verification
----------------------       --------------------------       ----------------------
* Biometric Passport         * Valid CoS / CAS Reference      * 28-Day Bank Statements
* National Identity Cards    * Endorsement Letters (Global)   * Appendix FM-SE Documents
* TB Certificate (if req)    * Sponsor Licence Validity       * P60, Payslips, Employer Letter

1. Proof of Identity, Nationality, and Status

• Valid Passport: Must contain at least one blank page for entry clearance vignettes and must be valid at the time of submission.
• Biometric Data: Digital fingerprints and facial photographs. Any mismatch between biographical records on Home Office databases and the identity document triggers an identity audit.
• Tuberculosis (TB) Screening Certificate: Mandatory for entry clearance applicants coming to the UK for more than six months from designated countries listed in Appendix T. Certificates must be issued by a Home Office-approved clinic.

2. Sponsorship and Educational Credentials

• Certificate of Sponsorship (CoS) / Confirmation of Acceptance for Studies (CAS): Must be assigned by an active, licensed entity. The caseworker verifies whether the CoS is 'Defined' (for overseas Skilled Workers) or 'Undefined' (for in-country applicants), ensuring the correct allocation was used.
• Academic and Professional Qualifications: Degrees relied upon for points or English proficiency must be accompanied by the original certificate and an official Ecctis comparability statement if obtained outside the UK.
• ATAS Certificate: Required for specific postgraduate study and research routes in science, engineering, and technology disciplines for non-exempt nationalities.

3. Financial and Maintenance Evidence

• Bank Statements: Must show that the required balance has been maintained continuously for the relevant 28-day period (finishing no more than 31 days before the application date). The account must be with a regulated financial institution where electronic verification is possible.
• Specified Employment Evidence (Appendix FM-SE): For spouse and partner applications, salaried employment requires:
  • Six months of payslips (if with the same employer earning above the threshold for six months or more under Category A);
  • Corresponding personal bank statements showing the exact net salary deposits matching each payslip;
  • A formal letter from the employer confirming employment, gross salary, contract type, and that the payslips are genuine.

4. Relationship and Cohabitation Evidence

• Official Certificates: Marriage or civil partnership certificates recognized under UK law (with certified English translations if issued abroad).
• Unmarried Partners: Evidence of cohabitation for at least two years in a relationship akin to marriage (or a demonstrable durable relationship), evidenced by joint utility bills, joint bank accounts, official council tax bills, or tenancy agreements addressed to both parties at the same residence across the qualifying timeframe.

Common Mistakes and Refusal Triggers

Immigration applications are frequently refused because of procedural and technical errors rather than intentional deceit. Caseworkers follow objective decision matrices where minor oversights can lead to a refusal.

1. Inadvertent Section 3C Lapses and Gap Creation

A critical mistake occurs when an applicant submits an in-country application after their existing visa has expired, or variations are made incorrectly. If an application is submitted even one day after the visa expiry date:

• Section 3C leave does not attach;
• The applicant becomes an overstayer immediately;
• The right to work is instantly extinguished;
• Continuous residence for the 5-year ILR path is broken.

2. Salary Threshold and Working Hours Miscalculations

Under Appendix Skilled Worker, employers and applicants often calculate salaries on gross headline figures without reconciling hours and the Standard Occupational Classification (SOC) 2020 minimums:

• The salary must satisfy both the absolute minimum general threshold (e.g., £38,700 for non-discounted new applicants) and the going rate for the SOC 2020 code, whichever is higher.
• Going rates are published based on a standard 37.5-hour working week. If an applicant works 40 hours per week, the minimum going rate must be pro-rated upwards. Failure to adjust the minimum salary for higher working hours leads to automatic refusal.
• Allowances (such as London weighting, accommodation allowances, or overtime) cannot be included to meet the baseline salary requirement unless specifically permitted under transitional arrangements.

3. Evidential Non-Compliance under Appendix FM-SE

Family route applications are subject to strict evidential rules under Appendix FM-SE. Caseworkers will refuse an application if:

• Bank statements miss even one day of the required six-month or twelve-month period;
• Payslips are provided without corresponding bank statements showing identical deposits;
• The employer letter omits any of the mandatory required statements (such as whether the employment is permanent or temporary, or the period over which the employee has been paid the stated level of salary).

4. Non-Disclosure under Part 9 (Suitability)

Failing to declare historical civil penalties, driving convictions, cautions, visa refusals for other countries (such as the USA, Canada, Australia, or Schengen members), or past UK overstaying is viewed by the Home Office as deception or false representation under Paragraph 9.7.1 or 9.7.2:

• Caseworkers run automated background checks via international data-sharing agreements.
• An omission is regularly interpreted as an attempt to deceive, resulting in a mandatory refusal and a 10-year re-entry ban, even if the underlying conviction or refusal was minor.

Edge Cases and Complex Legal Scenarios

Standard rules often encounter complex real-world variables. The following subsections examine scenarios requiring specialised technical handling.

Dependants: Family Rights, Care Workers, and Sole Responsibility

The ability to bring dependants (partners and minor children) varies significantly by route:

• Care Workers (SOC 6135) and Senior Care Workers (SOC 6136): Directives implemented in 2024 prevent newly sponsored care workers from bringing dependants to the UK. Only individuals who were already sponsored in these routes before the rule change and are extending or changing employers within the sector retain dependant rights.
• Student Route Dependants: International students cannot sponsor dependants unless enrolled in a postgraduate research programme (such as a PhD or research-based master's) or receiving a full government sponsorship scholarship.
• Sole Responsibility for Children: Where one parent applies to bring a minor child to the UK while the other parent remains abroad, the applicant must establish 'sole responsibility' under Paragraph 297/Appendix Children. Caseworkers require comprehensive evidence that the UK-based parent has made all major life decisions (education, medical care, religious upbringing) to the exclusion of the other parent. Shared custody or informal family care arrangements abroad generally result in refusal under this standard.

Continuous Residence and the 180-Day Absence Rule

For applicants on routes leading to settlement (such as Skilled Worker, Innovator Founder, Global Talent, and the 10-year Long Residence route under Appendix Continuous Residence):

• An applicant must not have been absent from the UK for more than 180 days in any rolling 12-month period during the qualifying qualifying residence period.
• Calculation Method: Caseworkers calculate rolling 12-month periods backward and forward from any date of absence, not on calendar or visa years.
• Permitted Exceptions: Absences exceeding 180 days are excused only in strictly defined circumstances, such as pandemic travel restrictions, assisting with a national or international humanitarian crisis, or life-threatening illness affecting the applicant or a close family member, all requiring contemporaneous evidence.
• Appendix Continuous Residence Modernisation: For applications submitted under the 10-year Long Residence route, absences starting before 11 April 2024 were subject to a historical 540-day total cap and a single-absence limit of 184 days. Any absence starting on or after 11 April 2024 is assessed under the rolling 180-day rule per 12-month period.

Transitional Rules and Grandfathering Provisions

When the Home Office increases financial thresholds or alters visa criteria, transitional provisions protect individuals already on the route:

• Skilled Worker Salary Thresholds: Applicants who were granted permission as a Skilled Worker under the rules in place before 4 April 2024 and have continuously held that status benefit from discounted baseline thresholds (based on the 25th percentile of earnings rather than the updated 50th percentile) when applying to extend their leave or settle, provided they do not break continuous leave.
• Appendix FM Minimum Income Requirement: Sponsors who lodged an application before 11 April 2024 under the historical £18,600 threshold remain assessed against that £18,600 baseline through subsequent extension and settlement stages, rather than the £29,000 threshold.

Employer Compliance, Right to Work, and Sponsor Duties

For corporate sponsors, employing a foreign national creates ongoing statutory duties under the Immigration, Asylum and Nationality Act 2006 and Home Office Sponsor Guidance:

• Right to Work Checks: Employers must perform digital checks via the Home Office online service for individuals holding an eVisa or BRP, or use an Identity Service Provider (IDSP) for British and Irish citizens. Manual checks are valid only for eligible paper documents (e.g., Irish passports). Performing a compliant check establishes a statutory excuse against civil liability.
• Reporting Duties via the Sponsor Management System (SMS): Sponsoring organisations must report specific events within 10 working days, including:
  • Failure of a sponsored worker to start employment on the stated start date;
  • Absence without pay for more than 4 continuous weeks;
  • Significant changes in job duties, working location, or salary;
  • Termination or resignation of employment.
• Civil Penalty Exposure: Employing an individual without lawful permission or in breach of their visa conditions carries civil penalties of up to £45,000 per illegal worker for a first breach, rising to £60,000 per worker for repeated breaches, alongside the potential revocation of the sponsor licence.

Switching Rules: Permitted and Prohibited In-Country Transitions

'Switching' refers to changing from one immigration category to another from inside the UK without departing to apply for entry clearance:

• Prohibited Switching: Individuals holding leave under the following categories cannot switch into any economic, family, or long-term category in-country:
  • Visitor visas (all sub-categories);
  • Short-term student visas;
  • Seasonal Worker visas;
  • Domestic Worker in a Private Household visas;
  • Individuals on immigration bail or temporary admission.
• Student Switching Restrictions: A Student visa holder can switch into the Skilled Worker route only if they have completed their course of study, or if studying a degree-level course or above, the start date on their CoS is after the course completion date, or they have completed at least 24 months toward a PhD.

Timing, Administrative Review, and Appeals

When a visa application is refused, the procedural mechanism to challenge the decision depends on whether the refusal engaged human rights or points-based criteria:

• Administrative Review (AR): Applicable for points-based and economic routes (Skilled Worker, Student, Global Talent) where a caseworker error is alleged. The application for AR must be lodged within 14 calendar days of receiving the refusal notice (7 days if detained), or within 28 days if applying from overseas. New evidence cannot be introduced unless it proves a caseworker error.
• Statutory Right of Appeal: Available primarily for human rights applications (Appendix FM, Article 8 claims) and EU Settlement Scheme decisions. The Notice of Appeal must be submitted to the First-tier Tribunal within 14 calendar days of the decision date for in-country decisions (28 days for overseas decisions).

Strategic Considerations for Applicants and Sponsors

Whether an applicant is seeking to enter the UK, extend leave, or secure permanent settlement, strategic planning is essential:

1. Monitor Status and Changes Digitally: With the transition to eVisas, all visa holders should maintain an up-to-date UKVI account linked to their current passport. Mismatches between travel documents and the digital record can cause travel disruption at the border.
2. Maintain Ongoing Records: Keep contemporaneous records of accommodation, employment, tax filings, and travel itineraries. Gaps in documentation complicate future 5-year or 10-year settlement applications.
3. Plan Application Timelines Carefully: Never wait until the final days of a visa to lodge an application. Preparing documentary evidence, English language testing, and Ecctis verifications often takes weeks, and missing an expiry date terminates Section 3C protection.

Practical Next Steps

To determine the exact legal requirements for your circumstances, review your current immigration documents, passport expiry dates, and the specific Appendix of the Immigration Rules governing your intended route on GOV.UK. Identify the qualifying criteria, assemble the mandatory supporting evidence in the specified formats, and verify that all salary or financial calculations comply with the thresholds in force on the date of submission.
