What Is the UK ETA?

The UK ETA is a digital travel authorization, much like the US ESTA or Canada’s eTA. It is electronically linked to your passport and required for short visits to the UK.

• ✅ Entirely online — no embassy visits needed

• ✅ Linked directly to your passport

• ✅ Valid for 2 years (or until your passport expires)

• ✅ Allows multiple entries during its validity

• ✅ Covers visits up to 6 months for tourism, business, family visits, short-term study, or transit

Who Needs a UK ETA in 2025?

You’ll need a UK ETA if you are:

• From a visa-exempt country (such as the US, UAE, EU nations, and others).

• Visiting the UK for tourism, business meetings, short study programs, family visits, or transit.

You do not need an ETA if you are:

• A British or Irish citizen

• A UK resident with indefinite leave to remain

• Already holding a valid UK visa

UK ETA Application Requirements

Before starting your application, ensure you have:

1. A valid biometric passport (machine-readable, from a visa-exempt country).

2. A recent digital passport photo (plain background, clear face, meets UK standards).

3. Personal information — full name, date of birth, nationality.

4. Travel details — reason for visit and intended dates.

5. Valid email address — this is where your ETA approval will be sent.

6. A debit or credit card to pay the ETA application fee.

How Long Does the UK ETA Take to Process?

Most UK ETA applications are approved within 48–72 hours, but delays can happen due to additional checks. To avoid stress, apply at least one week before your travel date.
