Can I extend my free visa in Thailand or obtain a different type of visa like a Non-O Retirement Visa?

If you entered Thailand with a Visa Exempt stamp, you can extend it for an additional 30 days at a local Immigration Office. You can also choose to exit the country and re-enter to receive another 30-day stamp. However, there is no official restriction on how many times you can do this, but repeated entries could lead to scrutiny from immigration officials. Additionally, if you meet certain requirements, you can apply for a Non-O Retirement Visa while in the country.
