How does the extension of a Non-B visa based on employment work in Thailand?

The process of extending a Non-B visa in Thailand typically allows for a full 1-year extension if all documents are in order. However, there could be cases where an Immigration officer might grant a 1-month extension first if additional information is needed or if the application is submitted late. This temporary extension, sometimes referred to as 'under consideration,' serves to keep the applicant's permission to stay valid while awaiting the necessary documents or decisions.
