To correct this problem, I hereby direct USCIS to take several steps to modernize and improve the immigrant visa process. First, USCIS should continue and enhance its work with the Department of State to ensure that all immigrant visas authorized by Congress are issued to eligible individuals when there is sufficient demand for such visas. Second, I ask that USCIS work with the Department of State to improve the system for determining when immigrant visas are available to applicants during the fiscal year. The Department of State has agreed to modify its visa bulletin system to more simply and reliably make such determinations, and I expect USCIS to revise its current regulations to reflect and complement these proposed modifications. Third, I direct that USCIS carefully consider other regulatory or policy changes to better assist and provide stability to the beneficiaries of approved employment-based immigrant visa petitions. Specifically, USCIS should consider amending its regulations to ensure that approved, long-standing visa petitions remain valid in certain cases where they seek to change jobs or employers. Thanks Again.
