What documents are needed to transfer a child’s visa to a new passport in Thailand?

"Should", "think", "would". Honestly, I'm not going to waste my time further trying to figure out what you have in your passport when direct answers are not being given, so I'm closing this post.

IF you have a visa ("the sticker"), you'd use both passports, and would do nothing at the immigration office.

IF you have an extension of stay ("the stamp"), you'll need to transfer the extension of stay from the old to the new passport. Different immigration offices have different policies, but this should work for all offices.

1. You'll need a letter from your embassy requesting the change from old passport number to new passport number

2. Photocopy each page of the old passport that have stamps or visas

3. Photocopy the data page of the new passport, and each page of the new passport that has stamps.

4. Go to the local immigration office and fill out at Transfer Stamp to A New Passport Form. Different immigration offices have different requirements.

5. There is *NO FEE* for this service. If you are asked for a fee, don't pay it.

Good luck.
