For foreigners who want to retire in Thailand, the country offers a variety of retirement visas. The non-immigrant O-A visa, sometimes referred to as the "long stay visa, is the most popular retirement visa.

You must be at least 50 years old, be free of any criminal convictions, have a specified amount of money in your bank account, or provide documentation of your monthly income in order to qualify for this visa. Depending on your nationality and the Thai embassy or consulate where you apply, the criteria change.

The non-immigrant O-A visa has the following financial requirements:

A Thai bank account with at least 800,000 baht ($25,000) in it for three months prior to applying for a visa
a minimum monthly income of 65,000 baht ($2,000) or an annual income and savings of at least 800,000 baht
After receiving the non-immigrant O-A visa, you are required to check in with the Thai immigration office every 90 days to confirm your address and status. Before the visa expires, you can also request a one-year extension of your stay.

The Thai government may at any time alter the specifications and guidelines for retirement visas; thus, it is advised to contact the Thai embassy or consulate in your area for the most recent information.
