Are there other immigration offices in Bangkok besides Changwattana for visa extension?

For 30 days extension you need to go IT Square laksi plaza. The main immigration is not far from that and hardly 2.5 km away from IT square

Actually the main immigration office at the government complex out on Chaengwattana Road is NOT where you go to get a 30 day extension on a visa exempt entry 😮 🙁

You go to the immigration office located at IT Square Laksi Plaza. That's the ONLY office in Bangkok to get 30 day extensions on visa exempt entries.

It's here



You also need to have a TM30 filed by your hotel or where ever you stay showing you're registered as staying in Bangkok. There are copy/photo shops next to the immigration office.
