F-1 SEVIS fee
All international students in initial F-1 status are required to pay a $200 SEVIS I-901 fee before applying for their F-1 visa. Students should pay the fee at least 3 business days prior to the visa appointment and bring the receipt of payment to the visa interview. Students should keep this receipt of payment for their records and have it on-hand when initially entering the United States.
Canadian students must pay the SEVIS fee and present proof of receipt at the border. Canadian students do not need to apply for a visa to enter the U.S.
