Is the multiple re-entry visa office at Don Mueang Airport open 24 hours, and what documents are needed?

Download and prepare your TM8 and attach photo before you go.I did this 3 weeks ago and it took about 10 minutes.

There is a small office room (combined with an overstay fine counter) just behind the passport control counters at DMK. It's open for 24 hours. Tell the officer at passport control that you need to get a re-entry permit there. He would direct you where you go.

Usually, you need 10-20 minutes plus. put some more in case the officers are not enough at that time of the day, around 4 am.

You will pay the fee of 3,800 baht for a multiple re-entry permit and a 200 baht service fee. If you bring all the necessary documents including photos, you may not have to pay the service fee.
