How can a Singaporean extend their TR Visa while preparing for a Smart S Visa in Thailand?

A TR visa is a tourist visa. You will not need insurance or proof of hotel reservation before applying. You *MAY* need a TM30 filed at your local immigration office.

Different immigration offices have different requirements, but all require the following:

1. Your passport and:

a. a copy of your data ("picture") page

b. a copy of your most recent visa (if you have one)

c. a copy of your most recent stamp

d. a copy of your departure card

2. A TM30, filed in the immigration office. [commonly asked]

3. The Extension of stay application form

4. 2x passport pictures

5. 1,900 THB.
