Can Undocumented Immigrants Fly Within the U.S.? What Illinois Residents Need to Know

For undocumented Illinois residents, the question of domestic air travel is not straightforward. Undocumented immigrants are not automatically prohibited from flying within the United States, but the risks involved depend heavily on individual circumstances—including immigration history, pending cases, and the documents available for identification.

Understanding those risks before booking a flight is essential.

 

 

Can Undocumented Immigrants Fly Within the U.S.?

Domestic air travel is not prohibited for undocumented immigrants, but it requires careful consideration. All passengers aged 18 and older must present acceptable identification at TSA checkpoints, and the current enforcement climate means that airport encounters with federal officers carry real risks.

Identification Requirements

As of May 7, 2025, travelers flying domestically must present a REAL ID or another federally acceptable form of identification. Acceptable alternatives include a U.S. passport book or card or a U.S. military ID.

For undocumented immigrants, obtaining a REAL ID or U.S. passport is generally not possible. However, a valid and unexpired foreign passport is accepted by TSA for domestic air travel and is the most commonly used identification option for non-U.S. citizens flying domestically.

Additional TSA Screening 

TSA’s primary role is transportation security, not immigration enforcement. That being said, TSA officers have discretion to conduct additional identity verification when a traveler lacks acceptable identification, which can lead to questioning, document review, and delays. Before traveling, it’s advisable to review current TSA identification requirements, as these can change.

 

Risks to Consider Before Flying

Although many undocumented immigrants travel domestically without incident, there are still potential risks associated with air travel.

 

What Documents Should Undocumented Immigrants Carry?

Carrying valid identification is important whenever possible. In addition to a foreign passport, undocumented travelers may benefit from carrying documentation related to any pending immigration proceedings, including:

• USCIS receipt notices
• Copies of pending applications
• Immigration court hearing notices
• Attorney contact information

Travelers should never present false or fraudulent documents. Doing so carries severe immigration and criminal consequences.

 

Alternatives to Air Travel

For those who determine that air travel poses too much risk, other options carry fewer identification requirements. Bus and train travel generally involves less stringent identity verification than flying. Ground transportation by any means avoids the airport environment and the federal law enforcement presence that comes with it.

 

 

How an Immigration Attorney Can Help

Domestic travel can be complicated for undocumented immigrants. A qualified immigration attorney can evaluate potential risks, explain current TSA and immigration policies, and help clients understand how travel may affect pending cases or future immigration options.

Legal guidance is especially important for individuals who:

• Have prior removal or deportation orders
• Have been previously detained by immigration authorities
• Are currently in removal proceedings
• Have pending immigration applications
• Have criminal arrests or convictions
• Plan to travel near border regions

Even routine domestic travel can raise unexpected legal concerns when immigration status is uncertain.
