I get a new passport soon, what happem with the old infomation, can I "put over"

some information?

Immigration?

Difficult?

What to thinks about?

Cost?

THANKS!

There is no cost, other than some photo copies, and it it easy. Your Embassy should provide you a letter to present to Immigration and information of what to do (but some don't seem to do this). Believe it is still an office upstairs in Bangkok where you take care of the transfer.
