I have received my retirement visa from the Thai consulate. It's a Non-Immigrant O-A multiple entry.
I will be flying out of Seattle with a one-way ticket and (hopefully) landing in Chiang Mai next week.
Will I be required to pay anything further while going through customs/immigration?
What will I be required to do while going through customs/immigration after getting off the plane?
Any issues getting one the plane with a one-way ticket? Any issues in Thailand?
And... will I be good for a year (stamp?) or will I have to go see immigration while I"m there?
Thanks
