H-1B Visa Stamping at U.S. Consulate Kolkata

Wait times at Kolkata track the india bucket published by the State Department. They fluctuate by ±50% within weeks. Use the live calculator on /visa-stamping for the current bucket median plus a 221(g) probability overlay. Interview-waiver (Dropbox) waits are typically 60-75% shorter than interview-required waits when you're eligible.

Under the 2024+ rules: prior visa must be in the same class, expired no more than 12 months ago, no prior 221(g), and not a first-time applicant. Class changes (e.g., H-4 to H-1B) disqualify even if all other criteria are met. Document drop-off at Kolkata: VFS Global VAC — Kolkata.

Third-country processing at Mexican and Canadian posts is no longer generally available to Indian and Chinese H-1B workers (September 6, 2025 policy change). Most non-citizens of those countries must now return to their home post — for India-chargeable workers, that means a post like Kolkata or another Indian consulate. UK and Western European posts still accept third-country processing for lawful residents of those countries.

Section 221(g) is a "provisional refusal pending administrative processing" — typically Security Advisory Opinion (Visas Mantis), employer/role verification, or document follow-up. Resolution can take 14 days to several months. You cannot return to the United States on your prior visa stamp during this period. Plan total funds and runway accordingly — see /departure-cost and /runway-calculator.

Standard H-1B documentation: DS-160 confirmation, MRV fee receipt, appointment confirmation, valid passport, prior visa stamp (if any), current I-797 approval, employer support letter (recent, with role/salary/start date), recent pay stubs (3 months), employment-verification letter, client letter or end-client information if applicable, education credentials, and a copy of the LCA. Bring originals plus one photocopy of each. Generate a customized day-of document script at /stamping-action-plan.

For interview-required cases: arrive 30 minutes before your appointment time. Earlier is generally not allowed — security may turn you away. Bring no electronics. For Dropbox/VAC submissions: arrive at the VAC during posted hours; the VFS system runs on its own schedule and tends to be efficient if your packet is complete.
