The F-1 visa is intended for individuals who wish to pursue academic studies in the United States at a Student and Exchange Visitor Program (SEVP)-approved institution. To qualify, applicants must obtain a Form I-20 from their school, provide evidence of sufficient financial resources, pay the SEVIS I-901 fee, and demonstrate non-immigrant intent. The visa remains valid for the duration of the student's academic program, including up to 12 months of Optional Practical Training (OPT) after graduation, with an additional 24 months for those in eligible STEM fields. The application process involves a visa fee of $185, a SEVIS fee of $350, and variable school fees. The difficulty level is considered moderate, mainly due to the interview process and the need to prove access to sufficient funds. Visa Agency assistance is generally required. Processing times typically range from a few days to several weeks, and the global approval rate is approximately 59%.
