Why does my Thai visa application require additional documents after submission, and can I change my application location?

The post discusses the frustrations of a user who submitted an application for a Thai visa but was later asked for additional documents, including a guaranteed letter, despite the absence of a Nepali embassy or consulate in Vietnam. Comments suggest that the applicant should procure the necessary documents, as the requirements are stipulated on the embassy’s website. Moreover, it has been reiterated that the application location cannot be changed and applicants should thoroughly read the requirements prior to applying.
