, you should also check with your immigration office to see how many days they require you have left on your current extension to apply for the in country Non-O visa. Most require at least 15 days left on the extension you're on now to do it. <- That's because it goes under consideration for 14 days before you go back.
IF you don't have enough time left on your current stamp apply for a 60 day covid extension BEFORE the 27th of Sept (the date the current program is expiring)
