Can I extend my tourist visa in Thailand and what are my visa options upon returning from the US?

>Can I extend my tourist visa again so I can remain in Thailand until the 24th?

If you have not used your 30 day extension of stay based on tourism, you can. You will need the following:

1. The applicant’s passport and a copy of:

a. The data “picture” page.

b. The most recent visa (if applicable).

c. The most recent entry stamp or extension of stay (if applicable).

d. The departure card (“TM 6”) that should be stapled in the passport.

e. The TM 30 filed at the local immigration office

2. The extension of stay application form (“TM 7”).

3. 2x passport sized (4cm by 6cm) photos.

4. 1,900 THB processing fee.

You will be given an extension of stay for another 30 days.

Overstaying is a crime, which could result in blacklisting. See 3/permalink/7/

If you already used your 30 day extension of stay based on tourism, if you apply for another extension of stay, it will be rejected, and you will have 7 days to leave the country. It will have no affect on acquiring future visas, extension of stays, or entries.

> When I return, do I have to apply for a visa when I am in the US? Or can I get an automatic 30 day tourist visa on arrival?

Your choice. You can enter on a 30 day visa exempt [NOT a visa on arrival], OR get a 60 day tourist visa. You *WILL* need a Certificate of Entry.

>I then plan to extend my tourist visa for the standard 30 days and then do the STV

You *CAN NOT* do an STV inside Thailand, you can only get the STV outside of Thailand. Remember too, the STV is employment prohibited.

(1) My 30 day tourist visa extension ends on 20th October.

Does this mean you entered Thailand and went to the Immigration Office to get a 30 Day Extension of Stay. As this is a one time extension, you can not get one again.
