The United Kingdom’s immigration system has undergone significant changes following Brexit (January 2020). The UK no longer participates in EU freedom of movement. Since April 2025, the UK introduced an Electronic Travel Authorisation (ETA) system for non-visa nationals. The UK controls entry across four constituent nations (England, Scotland, Wales, and Northern Ireland) and several overseas territories. Immigration is governed by the UK Visas and Immigration (UKVI) division of the Home Office.

2. Right of Abode and Automatic Entry

2.1 British Citizens

All British citizens have the right of abode in the United Kingdom and may enter freely. British citizens include:

• UK citizens born or naturalized in the United Kingdom
• British Overseas Territories citizens (BOTCs) who have ‘right of abode’ by specific registration
• Citizens of UK crown dependencies (Jersey, Guernsey, Isle of Man) in relevant circumstances

2.2 Irish Citizens

Irish citizens have special rights under the Common Travel Area (CTA) agreement between the UK and Ireland. Irish citizens may enter and live in the UK without restriction and do not require visas or ETA. This arrangement predates both EU membership and continues post-Brexit.

3. Electronic Travel Authorisation (ETA)

The UK Electronic Travel Authorisation (ETA) was introduced in phases, with full implementation for most non-visa nationals in April 2025:

3.1 ETA Overview

• Fee: GBP 16 per person per application
• Validity: 2 years from date of issue (or until passport expiry, whichever is sooner)
• Allows: Multiple short trips to UK
• Each visit: Up to 6 months for tourism/family visits
• Application: Online at gov.uk/apply-electronic-travel-authorisation or via UKVI app
• Processing: Usually within minutes to a few hours; up to 3 working days

3.2 ETA Eligible Countries

The following nationalities require an ETA (not a visa) for short-stay visits to the UK. These are the ‘non-visa nationals’:

Europe & Americas	Asia-Pacific	Middle East & Others
Andorra	Australia	Bahrain
Argentina	Brunei	Israel
Brazil	Canada	Kuwait

All EU member states	(27 countries)

Note: Citizens of these countries visit without a visa but MUST have ETA authorization before boarding a flight or vessel to the UK (from April 2025).

4. Visa National Countries

Nationals of countries not listed as ‘non-visa nationals’ must apply for a UK visa before travelling. These are called ‘visa nationals.’ The majority of countries in the world are visa national countries. Notable visa national countries include:

• China — Chinese passport holders require a visa (however, see BIVS provision below)
• India — Indian passport holders require a visa (see BIVS provision below)
• Russia — Russian passport holders require a visa
• Pakistan, Bangladesh, Sri Lanka — Visa required
• Most African, Middle Eastern (except listed above), and South/Southeast Asian countries

5. British-Irish Visa Scheme (BIVS)

The British-Irish Visa Scheme (BIVS) is a joint initiative allowing certain nationalities who hold a valid short-term Irish visa to also enter the United Kingdom on that same visa:

5.1 BIVS Countries

• China (Ordinary passport holders)
• India (Ordinary passport holders)

5.2 BIVS Conditions

• Must hold a valid Irish short-stay visa (including join family/travel type visas)
• Travel must be to both Ireland AND the UK (cannot be UK-only travel on an Irish visa)
• Valid for entry through the Common Travel Area
• Does not replace a UK standard visitor visa for UK-only travel

6. Non-Ordinary Passport Provisions

Nationals of visa national countries can sometimes enter the UK without applying for a full visa if they hold certain non-ordinary passports. Diplomatic and official passport holders from many countries can enter for short visits (typically up to 30 or 90 days) without obtaining a standard visitor visa.

Check the UK government’s official visa national list for specific provisions, as these vary significantly by country and passport type.

7. Transit Requirements

7.1 Airside Transit (DATV — Direct Airside Transit Visa)

Nationals of certain countries need a Direct Airside Transit Visa (DATV) to transit through UK airports, even if they do not pass through border control:

• Required for: Citizens of many African, Middle Eastern, South Asian, and other nationalities

9. Health Requirements

9.2 Immigration Health Surcharge (IHS)

• Children under 18: GBP 776 per year
• Paid upfront for the duration of the visa

10. Points-Based Immigration System

Since January 1, 2021, the UK operates a points-based immigration system (PBS) that treats EU and non-EU nationals equally:

10.1 Skilled Worker Route Points Requirements

• Offer of job from a UK Home Office-approved sponsor: 20 points
• Job at appropriate skill level (RQF Level 3+): 20 points
• Salary meets minimum threshold (GBP 38,700 for most, lower for shortage occupations and new entrants): 20 points
• English language skills at B1 level or above: 10 points
• Total: 70 points required (there are tradeable points for shortage occupations and PhD qualifications)

11. Common Travel Area (CTA)

The Common Travel Area is a long-standing arrangement between the United Kingdom, Ireland, the Isle of Man, the Channel Islands (Jersey and Guernsey), and their associated dependencies. Within the CTA:

• British and Irish citizens can move and reside freely
• No routine border controls between CTA territories
• CTA members cooperate on immigration enforcement
• Post-Brexit, the CTA continues to operate — Irish and British citizens are unaffected
• Northern Ireland (part of UK) and Ireland share an open land border

14. Notes for Travelers

The UK’s immigration rules are detailed and complex. Key points for travelers:

• ETA is required for most non-visa national visitors since April 2025 — apply well before travel
• Having an ETA or visa does not guarantee entry — Border Force officers have discretionary powers
• Immigration rules changed significantly post-Brexit — EU citizens no longer have automatic right to live and work in UK
• EU citizens who obtained pre-settled or settled status under the EU Settlement Scheme retain their rights
• For the most current information, always consult gov.uk/browse/visas-immigration before applying or traveling
