Those seeking to enter the United States in F-1 status with a Form I-20 or those seeking a change of status to F-1 within the U.S. must pay a SEVIS fee before going to the US Embassy or submitting documents to the Vermont Service Center. The fee must be paid at least 3 business days before the scheduled visa interview.
