ROCHESTER N.Y. (WROC) -- With looming concerns over immigration policy changes from President-elect Donald Trump, who's set to be sworn in Jan. 20, some U.S. universities are urging international students to be on campus before that happens. The University of Rochester and Cornell are among several universities issuing this message. According to UR leadership, students travelling abroad for the winter break should return to the U.S. before Jan. 20 because, "we do not anticipate re-entry requirements to the U.S. to change before January 20, 2025, which is when the new administration takes office."  NYSP: Drone sightings on the rise; email for tips available UR announced that current undergraduate students will be able to move into their dorm rooms Jan. 16, 2025, and new, exchange, leave of absence and study abroad students will be allowed to move in Jan. 17, 2025. Officials advised international students to review these guidelines should they look to travel and come back. Trump stated that on his first day in office he intends to crackdown on immigration policy. During his election campaign, Trump said “On day one, I will launch the largest deportation program in American history," adding that he would lean on local law enforcement and federal agencies to help carry out his plans.

Cornell, issuing similar guidance to its international students as UR, stated "a travel ban is likely to go into effect soon after inauguration. The ban is likely to include citizens of the countries targeted in the first Trump administration: Kyrgyzstan, Nigeria, Myanmar, Sudan, Tanzania, Iran, Libya, North Korea, Syria, Venezuela, Yemen, and Somalia. New countries could be added to this list, particularly China and India. International students and scholars from outside of these “areas of concern” are not likely to be affected by a travel ban or targeted visa suspension. People who are not citizens of these countries but are in transit through them to the U.S. are unlikely to be affected." Cornell also announced that staffing shortages mixed with increased background checks at U.S. consulates could make visa processing times even longer.
