How can I obtain a TM30 for immigration and banking purposes as a spouse of a Thai national?

To obtain a TM30 form for immigration and banking purposes as a foreign spouse of a Thai national, you can either register your property online at https://tm30.immigration.go.th/ or visit your local immigration office with your wife. Make sure your wife brings her ID, house book (blue book), and marriage certificate. After submitting the TM30, request a residence certificate from immigration, as this document is often necessary for opening a bank account.
