it’s at the end of the 90 days when you get the one year extension when you sign up for the multiple reentry. Make sure you tell them that’s what you want.
It’s a very small amount of money to get them multiple reentry. Even if you think you’re only gonna leave once I would strongly suggest getting multiple reentry just even if you wanna go to another country for a short visit.
I flew to Cambodia and applied online the day I got there. 14 days later I had my visa and returned to Thailand. And hotels are incredibly cheap in Cambodia!
I have AT&T. Was very important for me to have my exact same number for all of my USA contacts even though I live in Thailand. Basically, I pay $120 a month extra. I know that’s a lot, but I still can get all of my bank notices in my two factor authentication messages. It’s worth it to me.
