What options does a guardian visa holder have when their visa is about to expire in Thailand?

A guardian visa holder in Thailand may have limited options if their visa is about to expire. One possibility is to apply for a yearly extension based on raising foreign children in Thailand, which requires having 500,000 baht in a Thai bank account for 30 days prior to the application. Alternatively, if they are currently under an amnesty, they could wait for government guidance on next steps when the amnesty period ends.
