Can I apply for a 60 Days Tourist Visa (TR) in a third country when I'm a US passport holder in Thailand?

It is possible for US passport holders to apply for a 60 Days Tourist Visa (TR) from a third country, but there might be complications. Various comments suggest it is generally achievable, though applicants may face skepticism from visa authorities regarding their tourist status if they have been in Thailand for an extended period. The process often varies based on nationality and the specific country's visa rules. Additionally, applicants may need to provide proof of a return flight. Some individuals have successfully gone to neighboring countries, like Vietnam, to secure their visa, but others noted different requirements exist based on the laws of the country where they apply.
