USCIS is open despite January 2018 government shutdown
From USCIS: The current lapse in annual appropriated funding for the U.S. government does not affect USCIS’ fee-funded activities. Our offices will remain open, and all applicants should attend interviews and appointments as scheduled.
Some USCIS programs are affected until they receive appropriated funds or are reauthorized by Congress. These include:
• EB-5 Immigrant Investor Regional Center Program. Regional centers are a public or private economic unit in the United States that promote economic growth. USCIS designates regional centers for participation in the Immigrant Investor Program.
• E-Verify. This free internet-based system allows businesses to determine the eligibility of their employees to work in the United States.
• Conrad 30 J-1 doctors. This program allows J-1 doctors to apply for a waiver of the two-year residence requirement after completing the J-1 exchange visitor program. The expiration only affects the date by which the J-1 doctor must have entered the United States; it is not a shutdown of the Conrad 30 program entirely.
• Non-minister religious workers. This special immigrant category allows non-ministers in religious vocations and occupations to immigrate or adjust status in the United States to perform religious work in a full-time, compensated position.
