What is a VAC in the US visa process and is it mandatory before my interview?
A VAC, or Visa Application Centre, is where your biometrics, meaning fingerprints and a digital photo, are collected for a US visa. It is also called an OFC appointment. Yes, it is mandatory, and in India it must happen at least 72 hours before your consular interview.
A VAC, short for Visa Application Centre, is the mandatory step where your biometric data, meaning your fingerprints and a digital photograph, is collected for your US visa. You will also hear it called an OFC, or Offsite Facilitation Center, appointment. Yes, it is compulsory, and it must be done before your in-person consular interview, never on the same day.

| 72-hour gap in India | A minimum 3-day gap between biometrics and interview |
| Purpose | Identity verification and biometrics only, no interview |
| Who conducts it | Third-party staff, not consular officers |
Documents and What to Expect
| Bring or Expect | Detail |

My Advice
Book your VAC slot for at least three full days before your interview, because missing the 72-hour rule in India can derail your whole timeline. Carry every original document, since you will simply be turned away without them. On the day, avoid tinted glasses and make sure your hands are free of cuts or fresh mehndi, so your fingerprints scan cleanly on the first attempt.
