Apart from passport and photos required in order to extend the visa on arrival for 30 days, is proof of new air ticket, insurance extension, and accommodation also required? Can you apply three weeks before expiry?
TLDR : Answer Summary
To extend a visa on arrival in Thailand for an additional 30 days, you typically only need your passport and photos. Documents such as proof of a new air ticket, insurance, and accommodation are not required. You can apply for the extension up to 30 days before your visa expires, and the extension will be added to the end of your current entry stamp. Additionally, some offices may ask for a copy of TM6 or TM30.
