Do Indians Need UK Transit Visa via Heathrow?

"Yes, as an Indian passport holder, you may need a UK transit visa if you are traveling to Canada via London Heathrow, but it depends on your situation and the type of transit:

1️⃣ Airside Transit (You stay in the airport, don’t pass UK border)

If you remain in the international transit area of Heathrow and your connecting flight is within 24 hours, you usually need a UK Airside Transit Visa (DATV).

Exemptions: You may not need a transit visa if you hold:

A valid Canadian visa (or certain other visas like US, Schengen, Australia, or New Zealand).

Certain residence permits from the UK, US, Canada, Australia, New Zealand, or EU countries.

2️⃣ Landside Transit (You pass through UK border or change terminals requiring UK entry)

You must apply for a Standard Visitor Transit Visa, even if your stay is just a few hours.

This applies if you need to collect luggage, change terminals, or check in again.
