Can someone extend their STV visa while in Thailand?

Just unnecessary additional info..

STV can be extended by only meeting STV extension requirements. You cannot apply for converting/changing type of any visa from STV.

Do yourself a huge favor...if you plan on staying the full 9 months...buy the insurance required for the full 9 months when you apply for the STV visa.

Expats are having difficulty obtaining the insurance extensions after they are in Thailand...with extensions being denied.

A recent report...

I was in Nonthaburi to extend my STV visa. Here's what the officer asked

1. Copy of passport

2. Copy of TM6

3. Copy of STV visa page on your passport

4. TM7, use the last updated one or get it from Immigration Office. With a photo affixed.

5. STM 2. Declaration that you're aware about overstay and the penalties.

6. ASQ certificate letter stating that you've completed 14 days quarantine.

7. Some kind of proof that you indeed stayed at the ASQ, i produced my ASQ hotel receipt ( room charges )

8. Health Insurance showing coverage amount, line by line items in details of IP, OP, Covid coverage amount.

9. Rental. To state clearly rental period when to when, at where, 4 signatures either passport or Thai ID at the end of agreement ( the usual standard contract ). If the rental's address is in Bangkok, you can only extend visa in Bangkok. Rental period should cover at least 3 months more.

And sign at every page.

Yes, but make sure you meet ALL the requirements before applying for the extension of stay
