Can I apply for another entry on a Non-B or Non-O dependent visa at immigration in Thailand before extending to a one-year visa?

The user inquires whether it is possible to apply for another entry on a Non-B or Non-O dependent 90-day single-entry visa while still in Thailand. A comment clarifies that it is possible to obtain a re-entry permit either at the immigration office or at the airport before leaving the country. However, the re-entry permit does not extend the 90-day validity of the visa; it merely allows the holder to exit and re-enter Thailand without losing their existing visa status. The holder must return to Thailand before the end of the 90-day period to apply for a year-long extension.
