Can a non-O spousal visa be extended if it expires in August?

A non-O spousal visa can potentially be extended if the requirements for a 1-year extension based on marriage to a Thai citizen are met. This application should be made before the current visa's expiration. Alternatively, if no extensions have been utilized during the current entries, a visit to a Thai family can grant a 60-day extension. Another option is to do a 'border-bounce' to obtain another 90-day entry stamp just before the current visa expires.
