Yes but you can't swap them at the border while doing a border bounce as the exit stamp, cambo visa and entry stamp must be in the same passport.. Which is what this thread is about.

Yes I have 2 passports. Can't swap at a Thai border if border bouncing. Can send a 2nd passport for a visa while here though.

1 reason is that you can double the life of 2 passports instead of using one all the time.

It is because of the volume of dodgy people perhaps....Yes I had to do one on a tourist exemption stamp last month. It is not too bad....3 hours in and out....

That is great. Wish Pattaya would follow suit. Worst immigration office around.

That could be a good idea...but only if within 24 hrs perhaps....??

Yes that is what I thought. :) No refusals.

Probably a good idea....No TM30 up there :)

Cristopher Svensson So you need the above (if same as Pattaya.....again I don't know as all offices are different).

For TM30..Copy of passport data page, TM6 departure card, arrival stamp and visa. 1 photo. Copy of House registration (Blue book) and ID card of the house owner. They will give you the form there to complete.

For extension....Then submit a copy of the TM30 slip (you receive) and apply for your visa extension as normal with 1 photo.

So you weren't refused then. You didn't officially submit the TM30 at that office and went to another with the required documents. If you turn up with all documents required at the Chonburi office there should be no problem as far as I understand it.
