What Is a C-1 Visa? Eligibility, Documents, and Application

A C-1 transit visa is a nonimmigrant U.S. visa that lets a foreign traveler pass through the United States on the way to another country, provided the trip qualifies as immediate and continuous transit with a prearranged onward itinerary.¹ You apply through a U.S. embassy or consulate, your stay is capped at 29 days or your scheduled departure (whichever comes first), and you cannot work, study, extend, or change status while you’re here.

Do You Actually Need a C-1

Many transit travelers don’t. Citizens of the roughly 40 countries in the Visa Waiver Program can transit on an approved ESTA, entering “In Transit” and their final destination in the address fields of the application.² Canadian and Bermudian citizens need no visa at all to transit.¹ If you already hold a valid B-1/B-2 visitor visa, that works for transit too.

The C-1 is for everyone else: travelers whose country isn’t in the Visa Waiver Program and who don’t already hold a U.S. visitor visa. The United States has no transit-without-visa program, so even a two-hour layover requires proper authorization.

Who Qualifies

Federal law defines the C-1 category as a foreign national “in immediate and continuous transit through the United States.”³ The State Department’s Foreign Affairs Manual reads “immediate” as a reasonably expeditious departure on a prearranged itinerary, with no unreasonable layover time. Any plan to visit friends, sightsee, or do more than sit in an airport or a nearby hotel overnight takes you outside the category and points you toward a B-1/B-2 instead.⁴

In practical terms, the consular officer wants to see three things: a confirmed onward ticket, proof you can enter your final destination (a visa for that country or a second passport, for example), and enough money to cover your transit. The officer will also weigh your ties to your home country, such as employment, family, and property, as a signal that you actually plan to keep moving.

Documents to Gather

A passport valid for at least six months beyond your intended stay in the United States.⁵
A confirmed onward ticket showing your departure from the U.S. and arrival at your final destination.¹
Entry authorization for your destination country, whether a visa, residence permit, or passport establishing legal entry.
A digital photograph meeting State Department specifications.⁶
Recent bank statements showing you can cover transit costs without needing unauthorized work.
An employer letter or other evidence of ongoing work at home, to support your intent to leave.

How to Apply

Start with the DS-160, the online nonimmigrant visa application, filed through the Consular Electronic Application Center. Enter your personal details, travel history, and transit itinerary, including flight information and the U.S. port of entry where you’ll connect.¹ Print the confirmation page; you’ll bring it to the interview.

Then pay the nonrefundable application fee of $185.⁷ Once payment is confirmed, schedule an interview at the U.S. embassy or consulate in your country. As of late 2025, C-1 applicants are not among the visa categories eligible for interview waivers, so plan on appearing in person. Staff will take digital fingerprints, and the consular officer will review your file and ask about your travel plans. If approved, the consulate keeps your passport briefly to affix the visa and returns it, typically within a few business days, though timing varies by post and season.

How Long You Can Stay

Your authorized stay is the shorter of 29 days or your next scheduled departure.³ In practice, CBP officers at the port of entry usually stamp C-1 arrivals with a departure date matching the connecting flight rather than the full 29-day window. Treat 29 days as a statutory ceiling, not a target.

What You Can’t Do on a C-1

The restrictions are among the tightest in U.S. immigration law. You cannot work, enroll in classes, or do anything beyond what’s needed to complete the transit. The Foreign Affairs Manual is explicit that layover privileges like visiting friends or sightseeing require a different visa.⁴

Federal law also bars C-1 holders from changing to any other nonimmigrant status while in the country; the C classification is specifically excluded from change-of-status eligibility.⁸ Extensions aren’t available either. If your onward flight is canceled and you need more time, work through the airline; the visa itself has no mechanism to buy extra days.

What Happens If You Overstay

Overstaying triggers real consequences. Unlawful presence of more than 180 days but less than a year makes you inadmissible for three years after you leave. A year or more of unlawful presence pushes the bar to ten years.⁹ These bars kick in when you try to come back, so a short overstay on a transit visa can lock you out for years. Beyond the formal bars, any overstay shows up in your immigration history and makes future applications harder to win.

Why Applications Get Denied

The most common refusal ground is Section 214(b) of the Immigration and Nationality Act, which presumes every nonimmigrant applicant intends to stay permanently until they prove otherwise. Overcoming that presumption takes strong ties to your home country — a job to return to, property, family — and a credible reason for the route you’re taking.¹⁰ If the officer thinks you could easily stay and have little pulling you home, the visa is refused however clean the paperwork looks.

Section 221(g) refusals are different: the application is incomplete or the officer needs more documentation. Those are often fixable by submitting the missing items so the consulate can reconsider. Criminal history, prior immigration violations, or fraud in any earlier visa application can also block approval.¹⁰

Other C Categories

The C visa family has several variants, and choosing the wrong one can get your application sent back.

C-1/D transit/crewmember, for travelers entering the U.S. as passengers to join a ship or aircraft they’ll work on.¹
C-2 for travel to and from the UN Headquarters District in New York under the Headquarters Agreement, with movement limited to the immediate New York City area.
C-3 for foreign government officials, their immediate family, and their staff transiting on official business.⁴

The plain C-1 is the one for ordinary travelers with no diplomatic role, UN affiliation, or crewmember duties. If your plan doesn’t fit the immediate-transit test, look at a B-1/B-2 visitor visa instead.
