One possible consequence, if legal status is allowed to lapse for many foreigners in the US who find it difficult to go home, is a potentially much larger number of undocumented people who become more reluctant to seek care and a much greater health risk https://twitter.com/c_szabla/status/1252579477940469760

At the very least such a situation would create a large class of people much like EU migrants in the UK after Brexit, with incredible uncertainty about their lives and careers hanging in the balance, and a good deal more economic disruption too

As this thread by @UnlawfulEntries points out, putting visa renewals in jeopardy ould also devastate a health system reliant on immigrants at a time when that would have the most adverse consequences https://twitter.com/UnlawfulEntries/status/1252578955531599875
