Is there a place to print documents within MTT?

Absolutely, you might be waiting at that that one printing shop at MTT a loooong time, if you're unlucky as I was a few weeks back. And I just needed a copy of my fresh 'next appointment' doc for a residence certificate. Have copies of all your docs in advance of your excursion there.

There is ONE shop at Muang Thong Thani Immigrations, it's the one that makes the copies, takes photos, sells water and mama noodles. It is SLAMMED with people in the morning and sometimes the queue for it is longer than the queue to get to the officer to do what you need to. :O

I'd certainly get that stuff printed out before you slog on out to MTT..

Yes, at the entrance of MTT is a print machine and you need Line installed on your phone. Send the documents in Line and they print from their device for you. But as said above now it will be really busy and I should go printshop.

There are printing shops there. But not sure they would do data from your phone (especially when expecting busy day).

You would get better service during you are in downtown area.

This might be a stupid question but what is MTT?
