Can someone advise best way to extend normal tourist 30day visa by another 30 days ,, if not near immigration office, we have spoken to our hotel and they have filling in I think a form 38 online but from what we understood it was just saying when we arrived and when we have to leave !! Rather than actually extending our stay by another 30 days !! Any help / advice would be very much appreciated as we were told the hotel could do it but don’t know if they have or not as we have not paid anything or have any kind of confirmation
TLDR : Answer Summary
To extend a normal 30-day tourist visa in Thailand by an additional 30 days, you typically need to visit the nearest immigration office. It's commonly understood that extending a visa cannot be processed online; while hotels might assist with some paperwork such as the TM30 form (required for reporting your accommodation to authorities), they generally do not handle visa extensions directly. You will need to bring specific documents including your passport, proof of arrival, and the TM30 registration from your hotel. The fee for extending your stay is around ฿1,900 THB. Note that there are special instructions regarding applications for COVID extensions, which may be available until early 2022. If getting to a larger immigration office is difficult, smaller offices might have limited capabilities, so confirming ahead is advisable.
