美國國土安全部(DHS)發布規則,正式取消了「身分期限」(duration of status (D/S))規則。重點摘要如下:
Fixed Admission Caps: Nonimmigrant students (F visas) and exchange visitors (J visas) will be admitted for the length of their specific program, not to exceed a maximum period of four years.
Mandatory Federal Extensions: Visa holders requiring additional time to complete an academic program must formally apply for an Extension of Stay (EOS) directly through U.S. Citizenship and Immigration Services (USCIS).
Reduced Departure Grace Period: The time allowed for F-1 students to prepare for departure, transfer schools, or change status following graduation is reduced from 60 days to 30 days.
Current nonimmigrant visa holders residing in the United States under the previous “duration of status” framework will transition to the new system automatically, with their authorized stay capped at a maximum of four years from the effective date of this rule.
