Biometric Border Screening: A Guide for Non-Citizens

You cannot opt out. Here is what you can still do.

The Hard Truth: As of December 26, 2025, all non-citizens entering or leaving the United States are subject to mandatory facial recognition scanning. You cannot opt out. Refusal may result in denied entry, denied boarding, or immigration consequences. Your biometric data will be stored for up to 75 years. This guide explains what's happening, what rights you still have, and what limited protective measures exist.

What Changed December 26, 2025

The Department of Homeland Security activated a final rule expanding CBP's authority to collect facial biometrics from all non-citizens [1]. This is now mandatory at every airport, seaport, and land crossing.

Who is affected:

  • All visa holders (work, student, tourist, any category)
  • Green card holders (permanent residents)
  • Visa Waiver Program travelers (ESTA)
  • Canadian citizens (previously exempt)
  • Children under 14 (previously exempt)
  • Adults over 79 (previously exempt)
  • Diplomats (most exemptions removed)

Who can opt out:

  • U.S. citizens only

What happens if you refuse:

  • Denied entry to the United States
  • Denied boarding on departing flights
  • Potential immigration consequences
  • Referral to secondary inspection
  • Possible visa issues on future applications

What Data Is Collected

At Entry and Exit

  • Facial photograph: Captured by CBP cameras, matched against existing databases
  • Timestamp and location: When and where you crossed
  • Travel document information: Passport, visa details
  • Flight/vessel information: How you traveled

Already in the System

If you've previously applied for a visa, crossed a U.S. border, or interacted with U.S. immigration, you likely already have records in:

  • IDENT/HART: DHS biometric database (fingerprints, facial images)
  • TECS: Border crossing records
  • ADIS: Arrival/departure information system
  • CLASS: Consular lookout and support system

Data Retention

  • Non-citizens: Up to 75 years in the DHS Biometric Identity Management System
  • U.S. citizens (voluntary): Discarded within 12 hours

Your grandchildren could still be affected by data collected from you today.

Who Sees Your Data

Biometric data collected at the border isn't siloed. It feeds into a broader surveillance infrastructure [2]:

  • ICE: Immigration and Customs Enforcement for interior enforcement
  • FBI: Cross-referenced with Next Generation Identification (NGI)
  • State Department: Visa adjudication decisions
  • Local law enforcement: Through fusion centers and information sharing agreements
  • Foreign governments: Through bilateral data-sharing arrangements

This data can be used for:

  • Immigration enforcement actions
  • Criminal investigations (even for minor offenses)
  • Visa revocation decisions
  • Deportation proceedings
  • Entry denial on future visits

The Current Political Reality

This guide was written during a period of aggressive immigration enforcement. The administration has:

Biometric border data is part of this apparatus. Plan accordingly.

What You Can Still Do

You cannot avoid biometric collection. But you can take steps to protect yourself in other ways.

Before Travel

1. Consult an Immigration Attorney

Before any international travel, especially if you have:

  • Any immigration history complications
  • Pending applications or petitions
  • Previous visa denials or entry issues
  • Concerns about your immigration status
  • Family members with immigration issues

An attorney can assess your specific risk and advise whether travel is advisable.

2. Reduce Your Digital Footprint

Border data is cross-referenced with other databases. Limit what else is out there:

3. Know Your Entry Rights

Even non-citizens have some rights at the border:

  • Right to remain silent (but not about immigration status for non-citizens)
  • Right to refuse consent to phone/device searches (but CBP may detain you or deny entry)
  • Right to ask for an attorney (but one won't necessarily be provided)
  • Right to not sign documents you don't understand

Green card holders have stronger re-entry rights than visa holders. Know your specific category.

At the Border

Document Everything

  • Note the date, time, and location of crossing
  • Note names/badge numbers of officers if possible
  • Write down what was asked and how you responded
  • If anything unusual happens, document it immediately after

Device Security

CBP can search electronic devices at the border. Protect yourself:

  • Review our border device security guide
  • Travel with a clean device if possible
  • Log out of sensitive accounts before arrival
  • Back up data and remove from device before travel
  • Encrypted data can still be demanded (but at least protects if device is lost)

What Not to Do

  • Don't lie — False statements to CBP can result in permanent entry bars
  • Don't physically resist — This escalates situations and creates legal problems
  • Don't destroy evidence — Deleting data at the border can be obstruction
  • Don't sign documents you don't understand — Ask for translation or explanation

After Entry

Monitor Your Status

  • Check your I-94 arrival record at i94.cbp.dhs.gov
  • Ensure your authorized stay period is correct
  • Keep copies of all entry stamps and documents

Report Problems

If you experienced issues at the border:

  • DHS TRIP (Traveler Redress Inquiry Program) for entry issues
  • DHS Office of Civil Rights and Civil Liberties for rights violations
  • Consult an immigration attorney before filing complaints

Privacy Protection Inside the US

The biometric data is collected. Now minimize other tracking:

Special Considerations for Green Card Holders

Lawful Permanent Residents (LPRs) have stronger re-entry rights than other non-citizens, but those rights are not absolute.

What you should know:

  • You generally cannot be denied re-entry based solely on refusal to submit to biometrics
  • However, refusal may trigger extended secondary inspection
  • Abandonment of residency can be an issue for long trips abroad
  • Criminal history can complicate re-entry regardless of biometrics

Before traveling:

  • Review your criminal record (even minor offenses)
  • Consult an attorney if you'll be abroad more than 6 months
  • Consider naturalization if eligible—citizens can opt out
  • Keep documentation of ongoing U.S. ties (tax returns, property, family)

The Naturalization Path

U.S. citizens can opt out of biometric collection at the border. If you're eligible for naturalization, this is worth considering as a privacy protection measure.

Requirements vary but generally include:

  • 5 years as a permanent resident (3 if married to U.S. citizen)
  • Physical presence and continuous residence requirements
  • Good moral character
  • English and civics test
  • Oath of allegiance

Naturalization provides:

  • Right to opt out of border biometrics
  • Cannot be deported (with very narrow exceptions)
  • Additional constitutional protections
  • Cannot lose status for extended travel abroad

This is a significant decision with implications beyond privacy. Consult an immigration attorney.

Fighting Back: Advocacy and Legal Challenges

Individual compliance doesn't mean acceptance. Organizations challenging biometric surveillance:

  • ACLU: Legal challenges to facial recognition programs
  • EFF (Electronic Frontier Foundation): eff.org
  • EPIC (Electronic Privacy Information Center): Policy advocacy on biometrics
  • Immigrant Defense Project: Immigration enforcement tracking
  • National Immigration Law Center: Legal resources

What you can do:

  • Support organizations legally challenging these programs
  • Contact your representatives (if you have them)
  • Document and report civil liberties violations
  • Share information with your community

The Bottom Line

If you are not a U.S. citizen, you cannot avoid biometric collection at U.S. borders. Your face, your timestamp, your travel patterns—all of it goes into a database retained for 75 years.

This is surveillance infrastructure operating at scale. It connects to FBI databases, to ICE enforcement systems, to local law enforcement. It's designed to track everyone who isn't a citizen, permanently.

You can't stop the collection. But you can:

  • Reduce your exposure in other databases
  • Know your rights at the border and inside the country
  • Consult professionals before travel
  • Document everything
  • Support legal challenges to these programs
  • Consider naturalization if eligible

The system is designed to make resistance feel futile. But compliance with collection doesn't mean surrender of all agency. Protect what you can. Know your rights. Help others do the same.

They're watching. But you're not powerless.
