Pakistan, July 18 -- The United States has introduced stricter rules for international student visas, replacing the long-standing "duration of status" policy with fixed admission periods. The new regulation will take effect on September 15. The changes will affect F-1 students, J-1 exchange visitors, universities, and employers across the country.

According to the Department of Homeland Security (DHS), most F-1 students and J-1 exchange visitors will receive a maximum four-year admission period. Students requiring additional time must apply directly to US Citizenship and Immigration Services (USCIS) for visa extensions instead of relying on their educational institutions.
