Yesterday, June 22, 2020, President Trump issued the anticipated Proclamation suspending the entry into the US of certain nonimmigrant visa holders. Specifically, the following new restrictions are in effect 6/24/2020:
This means if you are an employer with an employee abroad who was expecting to obtain an L-1 or H-1B visa in the coming months (including those individuals who are waiting for approval of their H-1B visas under the cap/lottery) you should expect that the employee will not be able to return to the U.S. until January 2021 at the earliest, even if in possession of an approved visa petition.
Beyond the language of the EO itself, individuals who are exempt and plan to enter the U.S. soon, should be prepared to be challenged at the port of entry. Individual immigration officers at the port of entry may or may not fully understand the details of the order, or the exceptions, and it would not be surprising that if a few try to apply it too broadly or too aggressively.
