Starting December 26, 2025, DHS removes all age restrictions for biometric collection at borders [1]. DNA collection authority expands for immigration applications—not routine border crossings yet, but the infrastructure's being built [2].
You want to visit family abroad? They get your face and all ten fingerprints—even if you're under 14 now. Need to travel for work? Iris scans at eight major airports. Foreign spouse needs a green card? DHS proposes DNA testing to "verify" your relationship [3].
There's no opt-out that doesn't destroy your life. Miss your flight. Get detained. Watch your visa application disappear into a black hole.
Here's the ugly truth: you can't stop them from taking your biometrics. But you can limit what else they harvest.
## What They're Taking (As of December 2025)
Per the Federal Register notices [4], the expanded definition of "biometrics" now includes:
- **Facial imagery** - Mandatory for all non-citizens at entry/exit
- **All ten fingerprints** - Expanded from two-print system
- **Palm prints** - New addition to the collection arsenal
- **Iris scans** - Rolling out at major airports
- **Voice prints** - For "verification and security"
- **DNA** - Proposed for relationship verification in immigration applications
- **Handwritten signatures** - Digital capture and analysis
This applies to:
- All non-citizens entering/leaving the U.S. (effective December 26, 2025) [5]
- U.S. citizens filing immigration applications for family members [6]
- Children under 14 (age restriction removed) [7]
- Green card holders at CBP discretion
- Visa overstay monitoring ($30 fee for stays over 29 days) [8]
## The Database Problem
Your biometrics don't stay at the border. They flow to:
- **DHS IDENT** - 260+ million identities
- **FBI Next Generation Identification** - Shared automatically
- **DoD ABIS** - Military biometric system
- **State Department** - Visa processing
- **Five Eyes Partners** - UK, Canada, Australia, New Zealand
- **Interpol** - 194 member countries
Once it's in, it's in forever. No deletion. No corrections. No recourse.
## Minimize the Damage: Before You Travel
### 1. Segregate Your Digital Life
Create a travel-only digital identity:
- Dedicated email for travel bookings
- Separate phone for international trips
- Different credit card for travel expenses
- Never link to your main accounts
Why? They correlate biometrics with digital footprints. Keep them separate.
### 2. Sanitize Your Devices
Before crossing any border:
- Factory reset your phone (seriously)
- Use a clean laptop with zero personal data
- Remove biometric unlock (Face ID, fingerprint)
- Log out of all cloud services
- Delete social media apps
They can force you to unlock devices. Don't give them anything to find.
### 3. Prepare Your Documents
Bring physical copies of:
- Return tickets
- Hotel reservations
- Meeting invitations
- Employment verification
The less they question you, the less data they create about you.
## At the Border: Damage Control
### Know What's Mandatory vs. Theater
**They CAN force:**
- Biometric collection (face, fingerprints, now DNA)
- Device searches at border (no warrant needed)
- Social media handle disclosure (for some visas)
**They CAN'T force:**
- Device passwords (for U.S. citizens)
- Cloud account access
- Biometric unlock (you can refuse, demand passcode)
### The DNA Collection Process
According to the proposed DHS rule [9], DNA collection would work as follows:
1. Cheek swab or saliva sample collected
2. Used to verify claimed genetic relationships for immigration benefits
3. Can be required from applicants, petitioners, beneficiaries, and derivatives
4. Results potentially shared with law enforcement databases
5. Enables familial matching (identifying relatives through DNA)
**If subjected to DNA collection:**
- Request written documentation of the legal authority
- Ask if it's mandatory or voluntary for your specific case
- Document the collection process
- Request information about data retention policies
### The Right Responses
When questioned:
- "I don't recall" beats lying
- "I prefer not to answer" is legal
- Silence is better than elaboration
- Never volunteer information
They're building a profile. Don't help them paint the picture.
## After Travel: Cleanup Protocol
### 1. Check What They Collected
File FOIA requests with:
- DHS (your travel records)
- CBP (border crossing data)
- FBI (biometric records)
Takes 6-12 months but shows what they have.
### 2. Monitor for Misuse
Watch for:
- Unusual visa denials
- Secondary screening increases
- Law enforcement contacts
- Identity theft indicators
Your biometrics are now attack vectors.
### 3. Document Everything
Keep records of:
- Collection dates/locations
- Officer badge numbers
- Irregular procedures
- System "errors"
You'll need this when things go wrong.
## The Nuclear Options
### For U.S. Citizens
**Minimize international travel.** Harsh but effective. Every trip adds data points.
**Drive to Canada/Mexico.** Land crossings have less biometric collection (for now).
**Use trusted traveler programs.** Global Entry means they already have your data. Might as well get shorter lines.
### For Non-Citizens
**Consider citizenship elsewhere.** If eligible. U.S. biometric requirements are extreme.
**Travel together.** Groups get processed faster, less individual scrutiny.
**Hire an immigration attorney.** For applications. They know which forms minimize data collection.
## Technical Countermeasures (Use at Your Own Risk)
### Facial Recognition Disruption
**Legal methods:**
- Dramatic makeup changes
- Facial hair changes
- Significant weight change
- Aging naturally (time defeats all systems)
**Don't bother with:**
- CV Dazzle makeup (they'll make you remove it)
- IR LEDs (detected immediately)
- Masks (instant red flag)
### Fingerprint Protection
**Before travel:**
- Heavy moisturizer (softens ridges)
- Avoid cuts/burns before travel
- Document existing scars
**During collection:**
- Request lotion if skin is dry
- Press lightly (poor quality = more attempts)
- Note if scanner is dirty
### DNA Minimization
**Can't prevent collection but can complicate analysis:**
- Mouthwash before collection
- Don't provide "extra" sample
- Request collection at end of screening
## The Long Game
### Political Action
Support organizations fighting biometric expansion:
- ACLU (litigation)
- EFF (technology policy)
- EPIC (privacy legislation)
- Your congressional representatives (yes, really)
### Legal Challenges
Current lawsuits challenging:
- DNA collection without conviction
- Facial recognition accuracy
- Data retention periods
- International sharing agreements
These take years but sometimes win.
### Alternative Documentation
Some countries issue:
- Biometric-free passports (rare)
- Privacy-enhanced ID cards
- Temporary travel documents
Research your options.
## When You Have No Choice
Sometimes you must travel. Family emergencies. Work requirements. Life happens.
When you can't avoid biometric collection:
1. Minimize all other data exposure
2. Travel quickly and directly
3. Document everything
4. Clean up after
5. Don't make it easy for them
Remember: They're collecting it anyway. Your job is to make sure that's ALL they get.
## The Uncomfortable Truth
We're past the point of preventing biometric surveillance. It's here. It's mandatory. It's expanding.
But you're not helpless. Every extra step they take, every additional form they need, every system error that requires manual intervention—it all adds friction.
Be the friction.
They want seamless surveillance. Give them complexity. They want correlation. Give them compartmentalization. They want your data. Make them work for every byte.

The surveillance state thinks you'll accept this as normal. That resistance is futile. That convenience beats privacy.
Prove them wrong.
