The Reality
Since March 2025, TSA has been sharing passenger manifests with ICE multiple times per week. Flying domestically now means entering an immigration enforcement database.
But airports aren't the only surveillance point. License plate readers cover highways. CBP operates checkpoints within 100 miles of borders. Your car, your phone, and your face are all trackable.
This guide covers what you can control—and what you can't.
Understand the Surveillance Landscape
Before making travel decisions, know what systems exist:
TSA → ICE
Passenger manifests shared multiple times weekly. Names matched against deportation databases.
License Plate Readers
80,000+ Flock cameras. 20 billion scans. ICE access without contracts.
CBP Checkpoints
Operate within 100 miles of any border or coast. Two-thirds of US population lives in this zone.
Facial Recognition
Clearview AI searches, airport biometrics, CBP photography at borders.
Flying: The Highest Surveillance Mode
Domestic flights are now immigration checkpoints. Here's what happens when you fly:
- Booking: Name goes to airline, then TSA Secure Flight program
- Check-in: Identity verified against government databases
- TSA screening: Name, flight details, timing logged
- Data sharing: Passenger manifest sent to ICE
- Database matching: ICE compares against deportation lists
- Potential intercept: If flagged, agents dispatched to airport
What You Can Do
- Consider alternatives: Ground transportation doesn't trigger TSA-ICE sharing
- Know your status: Consult an immigration attorney before booking
- Avoid booking far in advance: Less time for systems to flag and respond
- Choose direct flights: Fewer touchpoints, fewer database queries
What You Can't Avoid
- If you fly, TSA gets your data. There's no opt-out.
- If TSA has your data, ICE can access it. The sharing program is policy.
- ID requirements: As of May 2025, REAL ID is required for domestic flights
US Citizens vs. Non-Citizens
US Citizens:
- Can opt out of facial recognition at airports (request manual verification)
- Not subject to ICE deportation (but can still be questioned)
- Photos deleted within 12 hours if biometrics captured
Non-Citizens:
- Cannot opt out of CBP biometric collection
- Data retained up to 75 years
- TSA data actively shared with ICE
- Flying triggers potential enforcement action
Driving: Surveillance Still Exists
Ground transportation avoids TSA-ICE data sharing. It doesn't avoid all surveillance.
License Plate Readers
Flock Safety operates 80,000+ cameras used by 5,000+ police departments. ICE has access without formal contracts. Other ALPR networks exist.
Where readers are common:
- Highway on-ramps and exits
- Major intersections
- Toll roads and bridges
- Shopping centers and parking lots
- Police vehicles (mobile readers)
- Hidden in traffic infrastructure
What they capture:
- License plate
- Time and location
- Direction of travel
- Vehicle make, model, color
- Distinguishing features (bumper stickers, roof racks)
Reducing Exposure
- Understand coverage: Urban and suburban areas have dense ALPR networks
- Vary routes: Consistent patterns are easier to track
- Check local policies: Some cities limit police ALPR use
- Consider vehicle: Rental cars add a layer of separation (but require ID)
CBP Checkpoints
Border Patrol operates interior checkpoints on highways within 100 miles of any border or coast. This covers:
- All of Florida
- Most of California, Arizona, New Mexico, Texas
- Entire East Coast and West Coast states
- Northern border states
- Areas near Great Lakes
At checkpoints:
- Agents can ask about citizenship/immigration status
- Brief stops are legal without individualized suspicion
- Extended detention requires reasonable suspicion
- Vehicle searches require consent, warrant, or probable cause
Your rights:
- You can remain silent (though this may extend the stop)
- You don't have to consent to vehicle searches
- Ask "Am I free to go?" clearly
- See our Know Your Rights: ICE Encounters guide
Buses and Trains: Lower Surveillance
Intercity buses (Greyhound, etc.) and Amtrak trains have less systematic surveillance than air travel—but aren't surveillance-free.
What's Different
- No TSA-ICE data sharing: Greyhound and Amtrak don't feed passenger manifests to ICE
- ID requirements vary: Greyhound doesn't always require government ID
- No security checkpoints: No TSA-style screening
What Remains
- CBP sweeps: Border Patrol sometimes boards buses near border areas
- Station stops: Agents occasionally conduct operations at bus stations
- Amtrak cooperation: Has historically allowed CBP operations on trains
- Card payments: Create transaction records
Reducing Exposure
- Pay cash when possible: Reduces financial tracking
- Avoid routes near borders: I-10 corridor, southern routes especially monitored
- Know station layouts: Some stations have heavier enforcement presence
- Travel during busy times: More passengers means less individual scrutiny
State-by-State Considerations
Where you travel matters. Some states limit cooperation with federal immigration enforcement. Others actively assist.
States With Stronger Protections
These states have sanctuary policies limiting state/local cooperation with ICE:
- California: Strongest state sanctuary law (SB 54)
- Illinois: TRUST Act limits ICE cooperation
- New Jersey: Sanctuary policy statewide
- New York: Sanctuary state policies
- Oregon: Original sanctuary state (1987)
- Rhode Island: Limits detainer compliance
- Washington: Keep Washington Working Act
What sanctuary policies mean:
- State/local police won't ask immigration status
- Jails won't hold people on ICE detainers beyond release date
- State resources not used for federal immigration enforcement
- Does NOT prevent federal agents from operating in the state
States With Higher Risk
These states actively cooperate with federal immigration enforcement:
- Texas: Anti-sanctuary SB4, aggressive state enforcement
- Florida: Anti-sanctuary law, ICE cooperation mandated
- Georgia: State-level immigration enforcement
- Arizona: History of aggressive enforcement
- Iowa: 2024 law allowing state immigration arrests
- Oklahoma: Strong ICE cooperation
What this means:
- Any police encounter can become immigration inquiry
- State resources actively used for ICE assistance
- Higher checkpoint and enforcement activity
- State databases may flag immigration status
Your Phone Is a Tracking Device
Your phone reveals your location constantly. This data is collected, sold, and available to law enforcement.
What Your Phone Broadcasts
- Cell tower connections: Logged by carriers, available via court order or purchase
- GPS data: Apps collect and sell location data
- Wi-Fi probes: Your phone announces itself to networks
- Bluetooth: Discoverable by nearby devices
Minimizing Phone Tracking
- Review app permissions: Deny location access to apps that don't need it
- Disable Wi-Fi/Bluetooth: When not in use, these create tracking opportunities
- Use airplane mode: When you don't need connectivity
- Consider a travel phone: A separate device with minimal apps
- Faraday bag: Blocks all signals when phone is inside
See our Phone vs. ICE guide for comprehensive mobile security.
Payment and Financial Tracking
Every card transaction creates a record: location, time, amount, merchant. This data is stored and can be subpoenaed or purchased.
Reducing Financial Traces
- Use cash: No electronic record created
- Prepaid cards: Less linked to identity (but not anonymous)
- Avoid rewards programs: Loyalty cards track purchase patterns
- Minimize receipts: Don't provide email for digital receipts
What Remains Visible
- ATM withdrawals: Location and time recorded
- Large cash purchases: May trigger reporting requirements
- Toll roads: Even cash lanes have cameras
Practical Travel Scenarios
Scenario 1: Cross-Country Trip, Avoiding TSA
Lowest surveillance option: Driving or bus, avoiding border regions
- Take northern routes (I-90, I-80) when possible—fewer checkpoints than southern routes
- Avoid I-10 corridor (heavily monitored)
- Fuel and supplies in cash
- Phone in airplane mode when not needed
- Plan route to minimize ALPR-dense urban areas
Trade-offs: Much slower, physically demanding, still some surveillance exposure
Scenario 2: Visiting Family in High-Risk State
If you must travel to states like Texas or Florida:
- Consult immigration attorney before traveling
- Know your rights at checkpoints
- Have emergency contacts ready
- Carry relevant immigration documents
- Avoid unnecessary police encounters (follow traffic laws strictly)
- Stay connected with trusted contacts who know your itinerary
Scenario 3: International Travel as Non-Citizen
Starting December 26, 2025, all non-citizens photographed at entry and exit.
- You cannot avoid CBP biometric collection
- Photos retained up to 75 years
- Data shared across DHS agencies
- Consult attorney about any travel outside US
- Re-entry may trigger additional scrutiny
What You Cannot Avoid
Be realistic about limitations. If you're subject to ICE enforcement, no amount of travel planning provides complete safety:
- Flying: TSA-ICE data sharing is policy. You cannot opt out.
- Driving long distances: ALPR networks are extensive. Routes matter, but coverage is everywhere.
- Border zones: Two-thirds of Americans live within CBP's 100-mile zone.
- Federal operations: Sanctuary policies don't prevent federal agents from acting.
- Data accumulation: Past location data, facial recognition matches, and records persist.
This guide helps reduce surveillance exposure. It doesn't eliminate it.
If You're Stopped
Know your rights and have a plan:
- Remain calm. Don't run, argue, or resist.
- You have the right to remain silent. You can say "I wish to remain silent."
- You don't have to consent to searches. Say "I do not consent to a search."
- Ask if you're free to go. If yes, leave calmly. If no, exercise your right to silence.
- If arrested, ask for a lawyer immediately. Don't sign anything you don't understand.
