Can a holder of an SETV from the Philippines extend their stay in Thailand beyond 59 days?

The statement "Period of stay not over 59 days according to bilateral agreement" on an SETV indicates that the initial permitted stay is capped at 59 days due to an agreement between Thailand and the Philippines. Generally, this means that the individual cannot apply for a standard 30-day extension; however, specific immigration policies should be confirmed with local immigration authorities as they may provide options or exceptions.
