They also asked for my Thai exit stamp but I explained in a joint pdf that I couldn't provide that because I went through the e-gates but provided pics of my paper 2boarding passes from Thailand to UK connecting in Dubai
But that e-ticket PDF showed it wasn't a one-way flight to Thailand it was a return back to Thailand, so they basically wanted proof that I took the flight to the UK and wasn't still in Thailand
That's really useful to know, thanks! Ive just completed the form but looks like it would be a long process because it's told me after submitting it that you could be asked for an interview and have to manually email a copy of your passport to them etc., even the Thai visa site itself seems better put together😭
might take a selfie holding a paper with the date on , next to my home address road name sign🫡 I'm a few hours away from London to take pics outside Big Ben
