UK Immigration Rules: How to Check the Requirements That Apply to You

Information checked November 2, 2026, against official UK government guidance. Immigration requirements can change; confirm the route and rules in force when you apply or travel.

The best way to find out which UK immigration rules apply to you is to start with the government's Check if you need a UK visa service, then read the official guidance and Immigration Rules for the route it identifies. Your passport or nationality is only one factor. The reason for your trip, intended length of stay, whether you already hold UK immigration permission, and whether you are applying from inside or outside the UK can change the answer.

For example, a person planning a short vacation may need a Standard Visitor visa, an electronic travel authorization (ETA), or neither. A person taking up a sponsored UK job generally needs to check a work route instead. Someone who already lives in the UK must consider their existing permission and whether they can extend or switch it. A checklist that skips these distinctions can give the wrong result.

UK immigration rules: the five details to check first

1. Nationality and travel document: Use the nationality and passport you will actually travel with. Dual citizenship, special passports, and Irish or British citizenship may change the entry requirements.
2. Main purpose: Identify whether you will visit, work, study, join family, transit, or seek another form of permission. Be specific about your planned activities.
3. Length and timing: Record your intended dates of entry and departure, course or employment start dates, and expected duration of stay.
4. Current status: Note any UK visa, indefinite leave to remain, settled or pre-settled status, or other existing permission. If you are already in the UK, record its expiry date and conditions.
5. Application location and history: Whether you apply inside or outside the UK, and whether you are extending an earlier grant or making a new application, can affect the applicable requirements.

Enter the relevant information in the official visa checker. Treat its result as a starting point for the correct route, not a decision that you qualify for permission. The government's application overview explains how your nationality, purpose, intended stay and personal circumstances shape the visa process.

Which UK permission might fit your situation?

This table is a route finder, not a complete list of UK immigration categories. Other routes have separate conditions, including certain temporary work arrangements, global talent categories, and the EU Settlement Scheme. Choose the route that matches your actual circumstances rather than assuming that a familiar visa name is available to you.

Visiting the UK: separate the visa requirement from an ETA

An ETA is travel authorization for eligible people who do not need a visa for their intended visit; it is not a work visa or a guarantee of admission at the border. Under the government's ETA exemptions guidance, British and Irish citizens do not need an ETA. People who already hold a UK visa or immigration permission, including certain settled or pre-settled statuses, generally do not need a separate ETA either. There are specific provisions for qualifying residents of Ireland and some airside transit travelers.

Do not assume that a visa-free entry rule also allows unrestricted work. The Visitor Immigration Rules restrict employment, running a business and other activities, with defined exceptions for permitted activities. Even if your nationality allows entry without a Visitor visa, you must still meet the Visitor requirements and may need an ETA.

Example: A traveler wants to attend two meetings and then sightsee for a week. The correct check is not simply “Can I visit without a visa?” It is whether those meetings fall under permitted visitor activities, which travel authorization applies to that passport, and whether the traveler can satisfy the general visitor conditions. By contrast, someone moving to the UK to work for that business should assess an appropriate work route.

Working in the UK: check the sponsor, occupation and salary together

For a new Skilled Worker application, the official guidance says you generally need an approved UK employer, a Certificate of Sponsorship, an eligible occupation and the applicable salary. As shown on the Skilled Worker job eligibility page checked on November 2, 2026, the usual salary test is at least £41,700 a year or the occupation's going rate, whichever is higher. Different thresholds or arrangements may apply to some health and education roles, certain lower-salary eligibility categories, and people extending or changing existing permission.

The four-digit occupation code matters. Two jobs with similar titles may have different codes and eligibility. Ask the employer for its sponsor status, proposed occupation code, Certificate of Sponsorship details and salary, then verify the appropriate rule. Meeting a headline salary figure alone does not prove eligibility. Other requirements, including English language and evidence, must also be checked.

Studying in the UK: verify your CAS, funds and evidence

Most applicants using the Student route need an offer from a licensed student sponsor and a Confirmation of Acceptance for Studies (CAS). They must also meet relevant English-language and financial requirements. The course requirements explain which studies qualify and when a CAS is needed. Some programs or applicants have additional requirements, such as an Academic Technology Approval Scheme certificate.

The official Student visa financial guidance, checked November 2, 2026, states a monthly living-cost amount of £1,529 in London or £1,171 outside London, for up to nine months, in relevant cases. Tuition requirements and exemptions differ by circumstance. Where applicants must show qualifying funds, the guidance explains the 28-day holding period and the timing of the financial evidence. Some applicants benefit from differential evidence arrangements, but may still be asked for proof.

Important timing point: The September 3, 2026 statement of changes (HC 584) includes Student maintenance changes scheduled to take effect on November 30, 2026. Do not apply a future threshold automatically to an earlier application or assume an older number will remain applicable later. Check the actual rule and transition provisions for the date you submit.

Joining family: why the relationship and application history matter

For a partner or spouse application, the family visa guidance addresses recognized marriages or civil partnerships and other qualifying relationships, plus English-language and financial evidence. The financial requirements page currently gives a usual combined income threshold of £29,000 a year for partners, but describes different arrangements for some benefit recipients and people extending permission first applied for before April 11, 2024.

Example: Two couples may both be applying as partners, but one is making a first application while the other is extending an earlier grant. Their financial rules may differ. Start with the route page that fits the application history, then check the relevant provisions of Appendix FM and its evidence requirements. Do not rely on a threshold copied from a different couple's experience.

How to verify which rule version is in force

The Home Office publishes a consolidated Immigration Rules collection and an index of route-specific appendices. The rules are amended periodically through formal statements of changes. The statements of changes archive is the place to verify what changed and when.

As of this article's November 2, 2026 review, the Immigration Rules collection reports updates through October 29, 2026. A particularly useful example is HC 584, dated September 3, 2026. It specifies different implementation dates, including October 8, October 29, November 30 and December 9, 2026, depending on the provision. It also contains transitional instructions for certain applications submitted before a change takes effect.

To check a proposed requirement, identify its route, paragraph or appendix, effective date, and transitional wording. A proposed bill, policy announcement or future-dated provision is not automatically the rule applying to your current application. When a later amendment appears, reread the specific route and implementation section rather than treating every headline as a system-wide change.

Budget for application fees, healthcare and supporting documents

Check the current Home Office visa fees tables for the correct route and application location. The table in effect from April 8, 2026 lists a six-month Standard Visitor application fee of £135; this is an example, not a universal visa charge. Fees may change and different durations or routes have different prices.

Some applicants must also pay the immigration health surcharge (IHS). On the official IHS cost page checked November 2, 2026, the annual amount shown is £1,035 for many adult applications and £776 for students, certain dependants and applicants under 18, subject to the specified categories, exceptions and visa duration. The charge is not required for every visitor or every immigration route. Calculate it using the actual guidance rather than adding a fixed amount to every application.

Depending on your route and history, other requirements may include English test evidence, certified translations, a biometric appointment, evidence of sponsorship or funds, and a tuberculosis (TB) certificate. The TB checking guidance bases its requirement on factors including the length of stay and recent residence in listed countries. Do not book a test merely because of nationality without checking the rule.

If you already have UK permission, check the conditions recorded on it

An eVisa is a digital record of immigration status and its conditions. If you have a UK Visas and Immigration (UKVI) account, use the eVisa guidance to access and confirm your status, work or study permissions, and linked travel document. The government says accessing an eVisa and setting up a UKVI account are free. Keeping passport details current can be important when traveling.

Before switching or extending, check the specific route's conditions and eligibility to apply from within the UK. An existing visa does not mean you can change to every category, and an ETA does not extend a person's right to live or work in the country. The rules for settlement, dependants and absences can also be different from the original entry requirements.

Practical pre-application checklist

• Use the visa checker with your actual passport and intended activity.
• Open the correct GOV.UK route page and check whether you are applying for entry, extension or switching.
• Verify the official Immigration Rules appendix, the date it applies and any grandfathering or transitional wording.
• Confirm sponsor, CAS, occupation code, relationship, financial evidence or language evidence as relevant.
• Check document validity, translations, TB and other country-specific requirements, rather than relying on a generic checklist.
• Calculate the current application fee, possible IHS and other applicable costs before committing to travel or services.
• Keep copies of the guidance version and application confirmation; recheck guidance immediately before submission.

When to get specialist immigration advice

Official online guidance is an effective first step for a straightforward case, but it may not resolve a previous refusal, an overstay, unusual travel documents, complicated family history, possible loss of status, or a contested interpretation of transitional rules. These situations deserve individualized advice before you submit. You can use the government adviser finder to locate a regulated immigration adviser or an appropriately authorized legal professional. An adviser can assist with a case but cannot guarantee the decision.

Bottom line: The correct UK immigration requirement is the one for your status, purpose, route and relevant date, not the newest rule mentioned in a headline. A useful final check is whether you can identify the official route page, the exact rule, its effective date, and the evidence you must supply. If any of those four elements is missing, revisit the official guidance before applying.
