Can I change my visa while on a 30-day extension after a 60-day TR visa?

The inquiry concerns the possibility of changing visa types while on a 30-day extension following the expiration of a 60-day tourist (TR) visa. Respondents clarify that a 30-day extension is treated the same as the original 60 days, but for a visa change application, it's important to apply with at least 14-21 days remaining on the visa. Additionally, one must ensure that the extension is granted before the initial TR visa expires to avoid overstaying.
