What is the best way to extend a 30-day tourist visa in Bangkok and how long can it be extended?

Plan well and safe travels. We are done.

You can extend it once for 30 days at a cost of 1900 baht at most local immigration offices, the process is pretty easy but around Thai holidays it can be super busy etc.

You are visa exempt…30 day stay. Can extend it another 30 day at immigration for a small fee or do a land crossing to a neighboring Cambodia (Laos requires a visa) and stamp back in for another 30 days

Once only. In Bangkok on a visa exempt entry that you have - not a tourist visa - you go to IT Square, Laksi Plaza to extend. You’ll get an extra 30 days added to your current entry stamp.

This is the hand out of what is generally required to get an extension based on tourism

If you showed up here without having bought a visa from a thai consulate before you winged your way here and were stamped in FREE for 30 days you got in on what's called a 'visa exempt entry' <- it's not a tourist visa, not a visa at all, just a free entry stamp

You can extend that once for 30 days for 1900baht.

In bangkok you go to the 3rd floor immigration office out at IT Square Laksi Plaza. (there are photo/copy shops next to immigrations).

This is where you go
