A bit of 20-20 hindsight to share. Have 6+ months left on US passport. Just renewed retirement visa, and got multiple re-entry stamp in Bangkok.

As expected, no problems or paperwork beside standard forms, bank letter, copies of bank book and passport. Took about an hour. Visa only goes to passport expiration date, but will roll over to full length in the new passport.

Not expected: the re-entry stamp only goes to the current passport expiration date, and does not roll over.

The moral: would have saved myself a trip to Immigration in 6 months, plus extra re-entry permit cost, if I had thought to renew my passport early, before going in to renew my retirement visa. Am posting in the hope it will help me to remember this 10 years from now

Or better yet about 9 years from now before your passport gets below one year.

You can't renew a visa. It's an extension of stay.

As soon as you got your new passport, go to immigration and they will transfer the stamps regarding your extension of stay and set the expiry-date of this permission of stay to the original date.

They may as well transfer your re-entry permit.

I just applied for a new passport with current passport having a few days over 9 months left.

My extension of stay is due next month. Done it early to save another trip to immigration to get the remainder of extension plus if I wanted to make trip across border to Laos (need 6 months on passport) it would of only been 3 months until I needed new passport anyway.

Will be making another day trip to Bangkok on the 31st to pick-up passport and get income affidavit.

As soon as you got your new passport, go to immigration and they will transfer the stamps regarding your extension of stay and set the expiry-date of this permission of stay to the original date.

They may as well transfer your re-entry permit.

Sorry, I was unclear. They will transfer the multi-entry stamp. However, they said they would not extend its validity for the full year (unlike the underlying visa).
