Pic on the page of your passport showing the last stamp, pic of you holding your passport, hotel res pic, flight confirmation pic, and for things that didn't apply (sponsor etc) pic of a hand written note saying 'none, not applicable'.
I presume you can, but I think there is a question for people not applying in their own country. If you start an application you will get to the question to see. If the application isn't complete and submitted within 14 days it drops off the system anyway.
Hi Gordon. In all 3 cases I didn't. I applied to London, but maybe different in other countries. As you have to have insurance for Thai Pass, that could be a reason. Perhaps someone else on here knows.
