For Indian applicants, the F-1 student visa has two clocks: the interview wait and the processing:

- Fees: $185 visa fee plus $350 SEVIS, $535 total, paid before the interview. - You can apply up to 365 days before your program start date, but you cannot enter the US more than 30 days before it. - Interview wait times at Mumbai, Chennai, Hyderabad, and Kolkata swing from days to months by season. Book the moment your I-20 arrives. - After approval, the passport usually returns in 3 to 5 working days. Sources: U.S. State Department F-1 visa processing time rewards the early. A $9.99 mock session with VisaMock costs less than one rescheduled flight, and it fixes the two minutes that actually decide your case.
F-1 student visa processing time for Indian applicants varies by consulate and season; book the interview the day slots open.
