I really hope the State Department continues issuing extensions and renewals.

I left the US in December 2019. Had I stayed, my non-immigrant visa would have expired in June 2020. In order to continue living in the US I would have had to apply for an extension to that visa or for an entirely new visa. Based on the reporting around this it seems possible that neither of those applications would have been approved and I would have been forced to leave the US in June 2020 at the latest.

If you know someone currently on a non-immigrant visa[0] you may want to reach out and make sure they're OK. I personally know a few people who set up their lives in the US with little consideration for what would happen if they lost their visas. I feel for them right now.

[0] That is: not a Green Card.
