Hey guys. I'm a South African, flying from Johannesburg to New York with a Layover in London(Heathrow). I'm not sure if I need a transit visa. I did check gov.uk, which says I may not need a transit visa if I have a US visa(which I do). Has anyone done this trip or a similar one? Or even if you just have knowledge on this, please let me know! Thank you!
