I applied via the London embassy on Friday morning, on Friday afternoon they asked me for my flight tickets back to Thailand, the e-ticket also had my flight details for my exit from Thailand last week. Now they've asked for copies of my boarding pass out of Thailand and the leaving immigration stamp, but I went through the E-gates! I have the boarding pass but no stamp, how else can I prove this? As I have a British passport there's no stamp into the UK either
