Hello again
Re: TM.30 filing
Sorry if this sounds obvious but I never had to deal with it before.
How do I proof to immigration that my landlord had me registered as a resident?
Do I need to bring a copy of the registration when dealing with immigration?
or
they will be able to see it in their system?
TLDR : Answer Summary
To prove your TM.30 registration as a resident to immigration in Thailand, you will need to bring a copy of the registration with you. Your landlord can provide you with a printout of the TM.30 registration, specifically one of the last two screenshots from the TM30 website or mobile application.
