On June 30, 2020 Presidential Proclamation 10052 was amended to clarify that individuals (and their dependents)  outside of the United States are suspended from seeking entry as an H-1B, H-2B, J-1, or L-1, unless they had a valid  H-1B, H-2B, J-1, or L-1 nonimmigrant visa on June 24, 2020 or are eligible for an exemption.  For example, an individual outside the U.S. with a valid B-1 visa on the day of the proclamation would be barred from receiving an H-1B, H-2B, J-1, or L-1 visa until the end of the year.
