I (Ukrainian) am traveling to the USA via Heathrow in London, UK (LHR). I was a little confused from reading the UK govt website, I'm not sure if my transfer is "airside" or not.
More details:
- My layover is 3 hours, arriving in terminal 3, departing terminal 5
- My baggage is checked to my final destination.
- I have a valid US B1/B2 Visa and a EU Residence permit.
Do I need to apply for a transit visa?
