Where should expats in Nonthaburi go for immigration registration and TM30 filing?

Anyone living in Nonthaburi, don’t make the same mistake as me; you don’t go to Muthong Thani but a different immigration office for registration and visa requirements. Accompanied landlord to Nonthaburi immigration office to register TM 30 as the online system is still not working.

For Nonthaburi at least, once you have filed your TM30, there is no need to refile a new one again it if you’re travelling domestically within Thailand and then returning back to Nonthaburi residence (as per statement from immigration officer).
