So as to not mislead anyone who didn't read the article, the section following your quoted text is:

> Researchers from lower risk countries have been told they could lose access beginning in either September or December if at that point they have been at the lab more than 2 years or, under a waiver, 3 years.

In other words: they're also looking to bar foreign nationals outside of that quoted list, which to my mind is less understandable.
