Many foreign nationals know that on June 22nd, Presidential Proclamation 10052 was issued. The Proclamation suspends entry into the United States of applicants for certain visas, including (among others) H-1B, H-2B, L-1, and L-2 visas. It does not apply to applicants who were in the US on its effective date (June 24th) and who already had a valid visa in one of the classifications mentioned above. It is nonetheless a sweeping ban applicable to hundreds of thousands of nonimmigrants, which has resulted in multiple lawsuits being filed against the federal government to enjoin it.
