President Trump is expected to issue an executive order in the next several days either eliminating, or significantly limiting, the availability of non-immigrant visas in categories of substantial importance to US companies (H-1B visas for specialty occupation workers, L visas for intra-company assignees, and other related categories), as well as eliminating or substantially curtailing the Optional Practical Training (“OPT”) program which currently allows foreign students graduating from US university programs to work for one to three years after their graduation. This Legal Update provides further detail on what it expected to be in the proclamation and in the subsequent rulemaking.
