Do I need to transfer my work visa to my new passport before a visa run?

@Nat****

, If you are on a single entry 90 day visa you do NOT need to go to the immigration office to transfer your stamps. You take BOTH passports to the border the next time you leave to get a new 90 day visa and they will stamp you out on the new one. You will then use that one to get the new visa from the thai consulate and not need your old passport anymore.

Okay, seeing as they O/P didn't answer back I'll explain the two different procedures;

IF you hold a year-long, multi-entry Non-B visa (that you got from a thai consulate in another country ) where you border bounce every 90 days you simply travel with BOTH passports getting stamped out and back in on the new one. You do this because the immigration office does NOT transfer a visa to a new passport.

IF you hold a year-long extension of stay (that you got from the immigration office in this country) where you do 90 day reporting you need to go to the immigration office with BOTH passports and they will transfer your current extension, entry stamp and re-entry permit to the new passport. Then you only need the new one.

hang about..

How about if you state whether you have a year-long, multi-entry Non-B visa (where you bounce out and back into the country every 90 days)?

OR

whether you have a yearly extension of stay from the immigration office?
