What happens to my visa if I apply for a COVID extension before my tourist visa expires?

The individual is seeking clarification about applying for a COVID extension to their 60-day tourist visa, which expires on April 10th. They are concerned that if they are not granted the COVID extension and only receive a regular 30-day extension, whether that would start from the date of their application rather than their current expiration date. Responses indicate that the 30-day extension would indeed start after the current visa expiry, and that applying for a COVID extension may require the prior 30-day extension.
