Just been told for the first time in 11 years at immigration that every time my wife and I return to Thailand from abroad she needs to submit a TM30. (I live in her house). Does this mean she has to physically schlep all the way to immigration with it or can she a) post it b) do it online c) sort it out when we arrive at Suvarnabhumi? Thanks.
TLDR : Answer Summary
When returning to Thailand, your wife must submit a TM30 form, which can be complicated by varying local immigration office requirements. While some offices may accept the form online or may not require it if there are no new TM6 landing cards, others might want it submitted physically upon return. It's suggested that your wife register for an online account to file the TM30 electronically and keep a record of the submission as proof. For specific guidance, it's best to check directly with your local immigration office to understand their exact requirements.
