About addresses in the application:
Permanent address: address where you are registered and/ or the address that is shown on the bank statement.
Current address (if different than permanent address): address in the country you are applying.
Address in Thailand: address of your accommodation/ house in Thailand. Where you are staying or where you will be staying.
TLDR : Answer Summary
In a Thai visa application, there are specific address requirements: the permanent address is where you are registered and should match your bank statement; the current address refers to where you are residing while applying; and the address in Thailand is where you will be staying during your time there.
