Do I Need a Visa to Visit the UK?
What you need to know
- •Citizens of many countries can visit the UK for up to 6 months without a visa.
- •The UK now requires an Electronic Travel Authorisation (ETA) for most visa-free visitors.
- •The ETA costs £10 and is valid for 2 years, allowing multiple visits.
- •Visitors cannot work in the UK. Business activities are limited to meetings and conferences.
- •If your nationality requires a visa, you must apply for a Standard Visitor visa before travel.
The UK has three categories for visitors: visa-free without ETA (British and Irish citizens), visa-free with ETA (most other nationalities that previously enjoyed visa-free access), and visa-required (everyone else). This guide explains which applies to you, what an ETA is, and the rules for visiting the UK.

Three Categories of Visitors
The UK groups visitors into three categories based on nationality:
- No visa and no ETA needed. British and Irish citizens can enter the UK freely under the Common Travel Area arrangement.
- No visa but ETA required. Nationals of countries that have visa-free access to the UK (such as EU countries, USA, Canada, Australia, Japan, and many others) now need an Electronic Travel Authorisation (ETA) before travelling. The ETA is not a visa — it is a simple digital permission.
- Visa required. Nationals of countries not on the visa-free list must apply for a Standard Visitor visa before travelling to the UK.
To check which category applies to you, use the GOV.UK visa checker tool.
The Electronic Travel Authorisation (ETA)
The ETA is a relatively new requirement that the UK has been rolling out since 2023. For a full guide, see our ETA guide. Here are the key points:
- Cost: £10 per application
- Validity: 2 years or until your passport expires, whichever is sooner
- Multiple entries: You can visit the UK as many times as you like during the validity period
- Stay per visit: Up to 6 months
- Application: Online via the UK ETA app or the GOV.UK website
- Processing: Usually approved within 3 working days, often within hours
The ETA is linked to your passport electronically. You do not receive a sticker or stamp. Airlines and border officers check your ETA digitally when you travel.
As of 2026, the ETA is required for nationals of most countries that previously enjoyed visa-free access, including all EU/EEA nationals, US citizens, Canadian citizens, and Australian citizens. The full list is on GOV.UK.
Countries That Need a Visitor Visa
If your nationality is not on the visa-free list, you must apply for a Standard Visitor visa before travelling. Countries that typically require a visitor visa include (but are not limited to):
- India, Pakistan, Bangladesh, Sri Lanka
- Nigeria, Ghana, Kenya (and many other African nations)
- China, Philippines, Indonesia
- Many Middle Eastern countries
- Several Central and South American countries
The full list changes from time to time. Always check the GOV.UK visa checker for the most current information.

How Long Can You Stay?
Most visitors can stay for up to 6 months per visit. There is no annual limit on the number of visits you can make, but you must not use visitor status to live in the UK effectively.
Border officers may ask questions if:
- You are spending more time in the UK than in your home country
- You make very frequent visits with short gaps between them
- You have previously overstayed
- You appear to be using the UK as your main place of residence
Some specialist visitor categories allow longer stays. For example, academic visitors may be permitted up to 12 months. Check the specific rules for your purpose of visit on GOV.UK.
Arriving at the UK Border
When you arrive in the UK, you will pass through border control. What happens depends on your nationality:
- E-gates: Citizens of many countries (including EU, USA, Canada, Australia, and others) can use the automated e-gates at major UK airports. You scan your passport and pass through without speaking to an officer. Your ETA or visa-free status is checked automatically.
- Manned desks: If you cannot use e-gates (or choose not to), you join the queue for a border officer. They will check your passport, ask about your visit, and may ask to see evidence of your return travel and accommodation.
Even if you have a valid ETA or visa, entry is not guaranteed. The border officer has the final say and can refuse entry if they believe you do not genuinely intend to visit, or if you cannot show you meet the visitor requirements.
Extending Your Visit
In most cases, you cannot extend a visit beyond 6 months. There are very limited exceptions, such as for medical treatment or specific academic purposes.
If you want to stay in the UK longer, you generally need to leave and apply for a different type of visa. You cannot switch from visitor status to a work or study visa from inside the UK (with very few exceptions).
Common Mistakes to Avoid
- Arriving without an ETA. If your nationality requires an ETA, you will be denied boarding by the airline. Apply before you travel.
- Working on a visitor visa or ETA. Even one day of work (paid or unpaid) violates the terms of your visit. This can result in a ban from the UK.
- Overstaying. If you stay beyond 6 months (or the period given by the border officer), you become an overstayer. This has serious consequences for future UK visa applications.
- Not having return travel. Border officers may ask to see evidence of your onward or return journey. Not having this can raise suspicions about your intentions.
- Insufficient funds. You should be able to show you can support yourself during your visit without working. Bank statements or credit cards can serve as evidence.
Next Steps
Use the GOV.UK visa checker to confirm whether you need a visa or ETA. If you need an ETA, apply online well before your travel date. If you need a visitor visa, start the application process early to allow time for processing and a biometric appointment.
