I'm staying at a monastery as a layperson on visa amnesty. I entered Thailand on Feb 28 with a visa exemption stamp. The abbot before has supported foreigners to stay longer and signed letters to the immigration office.

How would this process work in light of covid? Can I change to a volunteer or religious visa from within Thailand? How soon do I need to start this process? Are there any confirmed stories of someone on visa amnesty who successfully changed to a 3-month visa, or who were denied a 3-month visa?

Thanks in advance!
