If I understand the process for moving stamps to a new passport correctly (Non-O Over 50 Extension) at CW:

Enter Thailand with both passports, new passport gets stamped in.

At CW

* Need transfer stamp form and both passports

* Updated bank book and copy (bank book only. Not the full year report that takes a week from Bangkok Bank?)

* Copy of photo pages from each passport

* Copy of last arrival stamp (from the new passport) and last extension (from the old passport)

They move the stamp to the new passport.

And then, since I got my multiple re-entry permit at Suvarnabhumi, I need to take both passports there to move the re-entry permit, which I can do on my next flight out.

Am I missing anything?

Transferred stamps at Mahasarakham from old passport into new passport. Had all the copies from old passport plus a copy of new passport detail page. In 10.25 am....out 11.05 am.

I just want to share my good experience today at Hua Hin Immigration Office. 1.5 hours for transfering the old stamps in my old Swiss passport into the new passport, For yearly Visa renewing with TM 7 and TM 8 forms. And - I did not even ask for - they made an automatic 90 days report. Good Service!
