Can I renew my non-immigrant 'O' retirement visa in Myanmar and what do I need to enter Thailand after it expires?

If that plan described above does not work... Then enter Thailand by AIRLINE FLIGHT and get 45 days stamp on Arrival into Thailand.

When you get close to the ending date of your teaching contract in Myanmar, then apply for the Non O Visa as retiree and enter Thailand. Following up with your Thai immigration office for their requirements for the One year extension of stay as retired.

You CANNOT renew or obtain a One year extension of stay as retired in the Thai Embassy in Myanmar.

You might be able to get a New Non O Visa as retiree from the Thai Embassy in Myanmar if you have residency in Myanmar. ASK the Thai Embassy in Yangon.

Then to ENTER Thailand from Myanmar you must FLY into Thailand. As land border crossings into Thailand from Myanmar are CLOSED to foreigners.

I assume that you have the REQUIRED 800,000 Thai baht in a Thai bank account in your name only. As you currently have a One year extension of stay as retired.

The key to get the One year extension of stay as retired will be the timing of your visit to the Thai immigration office...do it ASAP upon arrival into Thailand.
