How the Calculator Works — Visa Interview Timing Formula

The calculator uses 2 inputs to find your booking deadline: the current interview appointment wait time at your chosen consulate, and a 10-day processing buffer for post-interview administrative review and passport return.

Book your appointment by the calculated date, if you want your visa in hand before your travel or programme start date. The formula is: Booking deadline = Target date − Wait days − 10 processing days. Wait time data is sourced from the U.S. State Department and updated monthly on this site.
