If your only reason for touching down in the United States is to catch a connecting flight, you might still need a visa — even if you never plan to leave the airport. The US is one of the few countries where transiting isn’t automatically visa-free, and getting this wrong can mean a missed connection or a denied boarding at your origin airport. Here’s exactly who needs a C-1 transit visa, who doesn’t, and how the process works in 2026.
What the C-1 visa actually covers
The C-1 is a nonimmigrant visa for someone travelling to another country whose only reason for entering the US is to pass through — an “immediate and continuous transit,” in US Department of State terms. It comes in a few closely related flavours:
- C-1: transit only (e.g. a connecting flight, or a cruise passenger whose ship calls at a US port without disembarking permanently).
- C-2: transit to United Nations headquarters in New York on official UN business.
- C-1/D: a combined visa for crew members transiting the US to join a ship or aircraft they’ll work on — the D covers the crew work, the C-1 covers getting there.
A C-1 does not let you conduct business, visit family, sightsee outside the airport, or work in the US. If you want to do any of that during a layover, you need a B-1/B-2 visitor visa instead — see our B-1/B-2 guide for that process.
Do you actually need one?
Most travellers transiting the US don’t need a C-1 specifically, because one of these usually applies instead:
- You’re from a Visa Waiver Program (VWP) country and use ESTA. Around 40 countries are VWP members, and their citizens can transit (and visit for up to 90 days) using an ESTA authorisation instead of any visa, including for transit-only trips.
- You already hold a valid B-1/B-2, or another qualifying nonimmigrant visa. A valid visitor visa generally covers transit too, so you don’t need a separate C-1 on top of it.
- You’re not from a VWP country and don’t hold a valid US visa. This is the group that genuinely needs a C-1 (or B-1/B-2) before booking a US-connecting itinerary — including many travellers from South Asia, Africa, and parts of the Middle East and Southeast Asia connecting through hubs like New York, Los Angeles, or Atlanta.
If you’re unsure which bucket you’re in, check your nationality against the current VWP country list on travel.state.gov before booking — airlines are required to deny boarding to passengers without the correct transit authorisation, so this is worth confirming weeks before departure, not at check-in.
Cost and how to apply
The non-refundable MRV (visa application) fee is US$185, the same base fee as a B-1/B-2 visitor visa, paid when you schedule your interview. Some nationalities also owe a reciprocity issuance fee on top of the MRV fee if the visa is approved — check your country’s reciprocity table for the exact figure, since it varies widely by nationality.
The application steps mirror any other US nonimmigrant visa:
- Complete Form DS-160 online and print the confirmation page.
- Pay the MRV fee and schedule a visa interview at your nearest US embassy or consulate.
- Attend the interview with your passport, DS-160 confirmation, photo, and proof of onward travel (your ticket to the final destination, and often evidence you’re admissible to that destination too — some countries won’t let you in without a return ticket or existing visa for them).
- If approved, the visa is issued in your passport; maximum stay under a C-1 is 29 days, which is far more than any real layover needs but sets the outer legal limit.
Interview wait times for C, D, and C-1/D categories have been running from under a month to over a year depending on the post, so book your appointment as early as your itinerary allows — see our US visa processing times guide for how to check current wait times at your specific consulate.
C-1 vs. ESTA vs. B-1/B-2: quick comparison
| | C-1 transit visa | ESTA (VWP) | B-1/B-2 visitor visa | |—|—|—| | Who it’s for | Non-VWP nationals transiting only | VWP nationals, transit or short visit | Anyone needing to visit, not just transit | | Fee | $185 MRV (+ possible issuance fee) | $40.27 | $185 MRV | | Lets you leave the airport | No — transit only | Yes, up to 90 days | Yes, up to the admitted period | | Requires an interview | Usually yes | No | Usually yes |
Common mistakes to avoid
- Assuming a layover never needs a visa. The US explicitly does not offer visa-free transit to everyone; it depends entirely on your nationality and existing visa status.
- Booking a self-transfer itinerary (separate tickets, re-checking bags) without checking transit rules. If you’ll clear US immigration and re-check in, you may need a full B-1/B-2 rather than a transit-only C-1, since technically you’re “entering” rather than remaining airside.
- Not carrying proof of onward admissibility. If your next stop also requires a visa, bring evidence you already have it — officers can deny boarding without it.
This is general preparation guidance, not legal advice — transit and visa-waiver eligibility rules change and vary by nationality, so always confirm your specific situation on travel.state.gov or with your airline before booking.
