Can I apply for a one-year extension on a Non-Immigrant OA visa after leaving Thailand before the first year ends?

The inquiry concerns the Non-Immigrant OA visa, specifically about leaving Thailand before the first year expires and the possibility of extending the visa for another year. It clarifies that exiting Thailand and re-entering just before the visa expiry allows for a new year's stamp. However, if one wishes to leave and return during the second year after the visa expires, a re-entry permit is required to maintain the entry stamp. If no exit from Thailand is planned during the second year, a re-entry permit is not necessary.
