I completed my application for DTV - nomad type online from the Royal Thai embassy London. There was no mention prior to my application regarding a couple of very important points : 1) can only apply if you are a permanent resident in Uk. ( I’m a nomad- what’s the point??). 2) Have to provide an e-ticket proof of flights from UK to Thailand. I’m already in Asia. Bloody stupid. Would never have applied from that embassy, pay the fee, if I had proper facts prior.
Anyway, hope this useful knowledge will help others to have an informed application process.
