What you’ll learn: Your legal rights when encountering ICE agents at airport security checkpoints, how AI-powered facial recognition is being deployed at these stations, and practical steps to protect yourself.
What you need: Nothing but awareness. This guide applies to anyone flying domestically within the US.
Starting March 23, 2026, ICE agents will staff some TSA airport checkpoints across the United States, according to Hacker News. This merges two previously separate functions: aviation security and immigration enforcement. The reporting, which builds on confirmed New York Times coverage from late 2025, raises serious questions about passenger rights and AI-powered surveillance at domestic airports.
What stands out here is the introduction of Mobile Fortify, an AI facial recognition app ICE agents carry on their phones. This tool can scan your face and flag you for suspicion, and it may be used at moments you don’t expect. Understanding how this AI system works and what the law says about it is now a practical skill for any domestic traveler.
📋 Step 1: Understand Who’s Searching You (and Why It Matters)
TSA checkpoint staff conduct “administrative searches” limited to one purpose: finding weapons, explosives, and aviation threats. That’s it. They can’t expand their search to look for evidence of other crimes or immigration violations.
ICE agents are different. They’re federal law enforcement officers who can make arrests for violations of federal law. This distinction matters because it changes what they can legally do to you at a checkpoint.
Why this matters: TSA staff who wrongly detain you face personal liability for assault, battery, false arrest, or kidnapping. ICE agents, as law enforcement officers, may receive “qualified immunity” from courts, making it much harder to hold them accountable.
📋 Step 2: Know Your Right to Stay Silent
ICE agents or TSA staff can ask you any questions they want. You don’t have to answer. No court has ever ruled that domestic airline passengers must answer questions or face sanctions for declining.
Tip: Silence is legally protected. Even if you say nothing, ICE agents must let you continue after only a “brief” delay, unless they develop “probable cause” (a high legal standard) to believe you’ve violated a law.
📋 Step 3: Understand “Reasonable Suspicion” vs. “Probable Cause”
ICE agents can only detain you briefly if they have a “reasonable articulable basis” to suspect a federal violation. To hold you longer or arrest you, they need “probable cause,” which is a higher bar.
Why this matters: These aren’t just legal terms. They’re the thresholds that determine whether an ICE agent can delay your flight by 30 seconds or change your life. Know the difference.
📋 Step 4: Protect Yourself From AI Facial Recognition
This is where AI enters the picture directly. ICE agents carry Mobile Fortify, a facial recognition and “suspicion-generating” app on their mobile devices. Here’s how it could be used against you:
- At ID verification stations, TSA requires you to remove your mask. ICE agents standing nearby may point their phones at you to scan your face through Mobile Fortify.
- ICE agents may also use Mobile Fortify at other unexpected locations throughout the airport.
Practical steps to minimize AI scanning risk:
- Wear a mask throughout the entire airport
- Pull your mask down briefly and only while standing directly in front of the ID verification staff person, not the camera
- If anyone starts pointing a cellphone at you, turn away and pull your mask back up immediately
- Keep mask-off time to the absolute minimum
Warning: No court has reviewed whether this opportunistic use of AI facial recognition at TSA checkpoints is legal. The practice exists in a legal gray zone.
📋 Step 5: Know That TSA Data May Be Shared With ICE
Reports indicate TSA has been passing airline reservation data to ICE to target domestic passengers. This means your booking information, not just your physical presence, could flag you before you even reach the checkpoint.
Why this matters: AI-powered systems like Mobile Fortify become far more effective when combined with pre-screening data. The combination of reservation targeting and real-time facial recognition creates a surveillance layer that didn’t exist at domestic checkpoints before.
📋 Step 6: Remember Your Right to Leave
TSA staff cannot physically stop you from leaving a checkpoint. If you decide to abandon your flight and walk away, they can’t restrain you. ICE agents, however, have broader authority to use force as law enforcement officers, with less chance of legal consequences.
Best practice: If you feel your rights are being violated, stay calm and state clearly that you do not consent to any search beyond standard aviation security screening.
🔮 What Comes Next
Lawsuits are expected, particularly if ICE agents seize domestic passengers based on airline reservation data. No court has yet ruled on the limits of ICE authority in this specific context, so the legal landscape will shift.
For AI specifically, Mobile Fortify represents a growing trend: law enforcement deploying facial recognition in spaces where people have limited ability to opt out. Airport checkpoints are mandatory for travelers, making them uniquely powerful locations for AI surveillance.
Your practical next steps:
- Follow organizations like the ACLU and EFF that track facial recognition policy
- Document any unusual interactions at checkpoints (notes, not recordings, in states with two-party consent laws)
- Stay informed as courts begin ruling on ICE checkpoint authority
- Consider contacting your congressional representatives about AI surveillance at domestic checkpoints
