Do I need visa for layover in USA on Delta?

Delta Airlines operates one of the largest flight networks in the world, which means many international travelers flying between regions such as Europe → Latin America, Asia → Canada, Australia → Caribbean, or Middle East → U.S. mainland pass through U.S. airports for transit.

The biggest question travelers ask is:

Do I need a U.S. visa if I’m only transiting through a U.S. airport on Delta, even if I never leave the airport?

Short Answer:
 Yes—in most cases you must have a U.S. visa or ESTA authorization, even for a short layover where you do not exit the airport.
The U.S. does not have an international transit zone like some countries. All passengers entering the U.S. must clear immigration, claim baggage (for most itineraries), and recheck before connecting.

This rule applies regardless of airline (including Delta), time spent in the airport, and whether your next flight is international.

Understanding U.S. Transit Requirements

Why the U.S. Requires a Visa for Transit

Unlike Singapore, Dubai, or many EU hubs, U.S. airports do not allow sterile international transit. The Department of Homeland Security requires every passenger landing in the U.S. to legally enter the country first, which means:

• Going through U.S. Customs and Border Protection (CBP)

• Presenting passport + visa/ESTA

• Collecting checked luggage (in most cases)

• Going through security again to board your connecting flight

Source: U.S. Customs and Border Protection confirms that transit passengers must meet U.S. entry requirements, even if they are not staying in the country.

Types of U.S. Visas and Permissions for Transit

Your required document depends on your nationality and travel purpose.

Who Is Eligible for ESTA Instead of a Visa?

Travelers from Visa Waiver Program countries, including the UK, France, Germany, Japan, Australia, New Zealand, South Korea, Spain, Singapore, etc., can travel with ESTA rather than applying for a visa.

You are eligible if:

• You hold a passport from a U.S. Visa Waiver country

• Your stay in the U.S. will be less than 90 days

• You hold a return or onward ticket

• No prior U.S. visa refusal, overstay, or immigration ban

 Even for a 45-minute layover, ESTA or visa is still required.

Step-By-Step: How to Apply for ESTA Transit Authorization

1. Visit the official DHS ESTA portal:

2. Submit the following:

   • Valid biometric passport

   • Return or onward destination flight information

   • Contact details

3. Pay the official fee (approx. $21 USD as of 2025).

4. Receive approval—usually within minutes, but allow 72 hours minimum.

If ESTA is denied → You must apply for a C-1 or B-1/B-2 visa at a U.S. embassy.

How to Apply for a U.S. C-1 Transit Visa

Can I Transit Without a Visa If I Don’t Leave the Airport?

No.

The United States requires all transit passengers to enter legally, even for through-ticketed Delta flights.

There is no airside transfer for international travelers.

What If My Layover Involves Two U.S. Cities?

Example: Delhi → New York (JFK) → Atlanta → Mexico City

• You must pass immigration at your first U.S. city.

• Claim bags and clear customs.

• Re-check to next Delta flight.

Even if your final destination is Mexico, Canada, or another country, U.S. entry documents are mandatory.

Overnight or Long Layovers on Delta

If you plan to:

• Explore the city during layover

• Stay in a hotel

• Visit friends/relatives

→ You need ESTA or B-1/B-2 tourist visa

A C-1 transit visa only allows through travel, not tourism.

If your layover exceeds 24 hours, a B-1/B-2 is strongly recommended.

What Happens if I Arrive Without a Transit Visa?

You may be:

• Denied boarding by Delta at departure airport

• Refused entry by CBP officers in the U.S.

• Deported back on the next available flight

• Charged penalties or flagged for immigration violation

Delta is legally required under U.S. regulations to refuse boarding if visa/ESTA is not verified.

Situations With Special Rules

1. Canada or Mexico Connections

Even if you are only connecting onward to Toronto, Vancouver, Cancun, or Mexico City:

You still need ESTA or visa.

2. International Transit to U.S. Territories

Puerto Rico, U.S. Virgin Islands, and Guam are U.S. entry points.

Visa rules remain the same.

3. Traveling With Family or Children

Each traveler—including infants—must have their own ESTA/visa.
