🛂 UK ETA for Americans: What You Must Know Before Traveling

As of 2026, all U.S. passport holders must obtain an ETA (Electronic Travel Authorization) before boarding a flight to London or any part of the United Kingdom.

🇬🇧 What is the UK ETA?

It’s a mandatory pre-travel authorization that verifies your identity and allows you to enter the UK for:

• Tourism
• Family visits
• Business trips
• Short studies
• Transits

It is mandatory even if you only transit through London Heathrow or Gatwick.

⏳ How long does it take?

Most applications are approved within 24 to 72 hours.
However, to avoid delays at the airport, it is strongly recommended to apply at least one week before departure.
