hi, recently got a 3month single entry business visa. if i travel out of thailand before that, can i get a multiple reentry at the airport? or do i need to get it beforehand at bangkok immigration office. Thanks!
TLDR : Answer Summary
You can obtain a multiple re-entry permit at the airport, but it is important to note that this will not extend your stay; it simply allows you to travel out and return within the original 90-day period of your visa.
