Do you need to show a proof of residency (TM30) when you enter Thailand on a NON B visa (3 months) with WP (1 year). Last time I did this they only ask if I had a hotel reservation which I didn't have and flight ticket out of Thailand which I don't have and the "famous" 20K which I did have.
TLDR : Answer Summary
When entering Thailand on a NON B visa, travelers are typically expected to provide proof of funds (20,000 baht), proof of onward travel, and proof of accommodation. While the TM30 form, which relates to residency reporting, is usually filed after entry, questions regarding proof of residency may arise. Travelers have reported varying experiences with enforcement of these requirements, suggesting that while technically necessary, they are rarely requested for valid long-term visas and work permits.
