What should I do at immigration when returning to Chiang Mai with a re-entry permit?

You fill in the re-entry permit number on the arrival/departure card under visa number, check if you get the same Admitted to Stay date as you had before and the next day you visit Immigration to update your address if you go back to the same address or make a new address registration if you stay on a new address. If you stay in a hotel/guesthouse you ask if they make the address registration and ask a print screen on the report. It is nothing new, not a new law and I have no clue what a credit card sized passport will do for you at Immigration. 3/permalink/5/

, if you go to Kodak with your passport they will reduce your details page and visa page down to credit card size and laminate it for you, this should be all you need. Black and white is 30bt.

This must be new rules because in the past immigration at the airport stamped my passport and I didn't need to do anything until reporting for my 90 days.

When I go for my 90 days all I need is my passport because I have a barcode in my passport and all they do is scan it.

Fòr all those concerned....it is best to keep updated...departure card, 90 day card and TM30 card IN YOUR PASSPORT at all times. These are important

when you come back into thailand you need to go to the immigration office and update a form called a TM.30. You have to do it within 24 hours of getting back to where you stay.

Nothing to do regarding to re-entry permit. Others are usual things TM 30, etc.
