Can someone on a marriage visa in Thailand transfer to another visa without leaving the country?

A friend is inquiring whether someone on a marriage visa in Thailand can switch to another visa without exiting the country during the COVID-19 pandemic. The general consensus is that while one cannot transition directly from a marriage-based extension to another visa type within Thailand, there are alternative options. One can maintain the current marriage extension until it is nearly expired and may potentially reclassify the extension based on a new reason, like employment. Additionally, there is an option to cancel the current extension and apply for a COVID-19 extension, provided it’s done before the specified deadline. It’s crucial for the individual to determine her marital status accurately before proceeding with any visa changes.
