American universities rank among the best in the world, so it is natural that Chinese with the means would want to study at them. But worsening relations between the United States and China have meant ever-more restrictions preventing such opportunities and the latest measure from the Trump administration will put some in immigration limbo. Without warning, authorities have announced foreign students cannot stay in the country if the schools they are attending move courses online due to Covid-19. If in-person teaching is available, they do not have to leave; but given concerns about the spread of the disease and how flights have been disrupted, there is every need for leniency.

Chinese students last year accounted for about one-third of the 1.1 million foreigners enrolled at American higher education institutions. How many are presently in the nation awaiting the start of autumn classes is not known, but those that are have been put in a difficult situation.

Chinese students have been either intentionally or unwittingly caught in the middle. Washington has to show understanding and work with Beijing for a solution.
