Hi guys! 2 quick questions when converting a tourist visa to a non b inside the country. Does the 15 days you need have to be on your original tourist visa or can they be on an extension? And are any countries barred from doing it at an immigration office like the Laos and Malaysian embassies? (Chiang Mai specifically, and I'm a Namibian passport holder). Thanks guys!
TLDR : Answer Summary
To convert a tourist visa to a Non-B visa in Chiang Mai, you typically need to have 22 days left on your current visa, and this requirement may apply to the initial tourist visa or its extension. Applicants should account for additional time needed for the application process, including making an appointment, as the process is slower in Chiang Mai compared to Bangkok. The nationality of the applicant may affect the process, but it's unclear if specific countries are barred. It's advised to visit the immigration office early to start the extension and application process.
