Apec Visa / ABTC card
Is there a limit to how many entries you can use this to enter Thailand? It's meant to be for short term business travel, and gets a 90 day visa each entry.
I have used mine 4 times in past 11 months, and spent about 60-75 days each visit, so about 8 months in total in Thailand.
Trips have had a genuine business reason although I have extended my stays here while waiting for other business trips within SEA.
TLDR : Answer Summary
The APEC Business Travel Card (ABTC) allows multiple entries into Thailand with a 90-day stay for each entry. There is no official limit on the number of entries. Many business travelers frequently visit Thailand without facing restrictions, though they may be questioned by immigration officers. Having legitimate business purposes and documentation can facilitate smoother entry.
