Hello,

I want to receive re-entry permit in Don Muang and use it in Poipet on my back way from Cambojia.

Is it correct way?

you will need to apply at the immigration office in Soi Suan Plu.

Don Muang only handles airline passengers with boarding cards.

Thanks,

can I apply it on Phuket?

You should be able to apply for a re-entry permit at most any "regular" Thai immigrations office (including Phuket). As Astral noted, the immigrations office at Don Muang only handles airline passengers.

You did not say what your present permission to stay in Thailand is. Assume

long(er) stay so you need a re-entry permit.

If you leave for Cambodia by air, after check-in at Don Muang go to building 1 (3rd floor?) with your boarding pass, pictures, fill in the application and allow 30 minutes.

Allow enough time to walk back and forth, evtl. more people applying. Once you have the re-entry you can come back over land.

Phuket airport I do not know, however, either BKK or HKT, I suggest go a few days earlier to the immigration office downtown, and get it there. Once it is in the p/port no need to worry.

Price Baht 1000 for single, 3800 for multiple.
