Hey I am in Thailand with a non b visa and i have lost my arrival slip that they give to fill on arrival. I have a copy of it with me but somehow misplaced the original what can be done kindly advise as i need to visit the immigration office in Bangkok to get my non b stamp etc.
TLDR : Answer Summary
If you have lost your arrival slip while in Thailand on a non-B visa, you can obtain a new one at the airport if you are traveling again. Alternatively, if you need to visit the immigration office to get your non-B stamp, having a copy of the slip may be helpful, but you should also be prepared to explain the situation to the immigration officers.
