While the administration of President Donald Trump has said his order suspending many work visas and extending a green card freeze will save the jobs of more than a half-million Americans, immigration experts Tuesday pointed out that the coronavirus pandemic has already choked off the flow of foreign nationals to the U.S.

That’s in part because the outbreak has closed overseas consular services for foreign citizens wishing to come to the U.S. as immigrants or workers, said Daniel Costa, director of immigration law and policy research at the Economic Policy Institute, a left-leaning think tank.
