@Tab ****
the thing is I haven't seen ANY "close the loop" stamps from people who got them recently when applying for the 60 day unable to travel due to covid extension. Everyone is still on either their previous extension (meaning they haven't applied for a new one yet) OR they're on an under consideration stamp (meaning they haven't gone back yet to get the extension stamp).
As a rule, extensions are effective starting from the expiration date of the current stamp you have in your passport. I think we're gonna hafta wait and see
