United States caps foreign student stays at four years

The U.S. has introduced new visa regulations limiting foreign student stays to four years, prompting 1.5 million international students and visitors to apply for federal extensions. This change is expected to impact academic institutions and international relations, as many students may leave earlier than planned, affecting research and cultural exchange. The policy shift underscores a tighter control on immigration, which could have long-term repercussions on the U.S. education system's global competitiveness and influence.
