Yesterday I went to the immigration here in Chiang Mai to do a 7 days extension of my visa (came to Thailand by air on 17th of July + 30 days extension valid until yesterday ). I don't actually understand what they did with the stamps, am I allowed to stay in Thailand until the 22nd (I'll leave on the 21st) or should I have gone out yesterday because they refused it ?
I was there with my girlfriend and she got the same stamps too, we went to ask and the immigration officer said we don't have to pay anything if we leave before the 22nd but honestly we didn't understand if he said that just to have us gone or because it is like that.
Any idea? What should we do ?
Sorry if someone already asked this but I couldn't find an answer
