Depends where you are from
[QUOTE=Franciscass;2623213]Tried but couldn't find answers.
How long can one stay using the Thailand pass.
Can the stay be extended once here.
Many thanks.[/QUOTE]Some people have 30 days and some have 45 days. They have special rules right now allowing you to extend your stay another 30 days with a quick trip the immigration office and a 1000 bht fee. I will be going to do that again and I think there is more involved the second time. I can report here when I find out how it works.
The Phuket office right off beach road in Patong was pretty easy. Get there before 3 pm because the lady who does the visa extensions leaves at that time. One note, let them do the visa copies there for 100 bht or whatever it is. The nearest place to get copies will take you an hour and / or cost you more than 100 bht in taxis. Several of us didn't understand that he could do the copies there and almost left to get them done near the hospital. It's much quicker and easier to have him do it.
