Can you switch from a Non-Immigrant B visa to an education visa in Thailand without leaving the country?

The process of switching from a Non-Immigrant B visa to an education visa in Thailand typically requires leaving the country. However, due to COVID-19, it may be possible to do this in-country. You need to cancel your work permit and obtain documentation from your employer confirming your last working date. After canceling your extension based on employment, you can apply for a 60-day COVID extension. You'll then need to gather documentation from your university to apply for an in-country 90-day Non-ED visa. It's important to coordinate with both your university and the immigration office to ensure this process is feasible.
