Having a green card gives you significant protections as a lawful permanent resident, but it doesn’t shield you from questioning, detention, or removal proceedings. A routine traffic stop, an old criminal matter, or signing the wrong document at the wrong moment can put your status at risk. Here’s what our clients need to know before traveling anywhere in the U.S.
Always Carry These Documents
Federal law requires every green card holder age 18 or older to carry their Form I-551 (green card) at all times and produce it if an immigration officer asks. Leaving it at home isn’t a minor slip — it’s a federal misdemeanor that can carry a fine or even jail time. Good news for flyers: your green card is already accepted by TSA, so you don’t need a separate REAL ID to board a domestic flight. It’s still smart to carry a secondary form of ID, such as a REAL ID-compliant driver’s license or a valid passport, and to keep your immigration attorney’s phone number written down on paper rather than relying on your phone.
What Happens at the Airport
TSA passes passenger information to ICE, which checks it against removal orders and outstanding warrants. If there’s a match, ICE agents — who already have a presence at many U.S. airports — can be waiting. If you have a pending removal order, an open warrant, or any criminal history, talk to your attorney before you book that flight.
You should also know that facial recognition screening has expanded significantly, now used at dozens of airports nationwide as part of a broader push to unify DHS biometric systems. You have the right to decline it for domestic travel — simply tell the officer you’re opting out and would like manual ID verification instead, and ask for a supervisor if you’re refused. One caveat: earlier facial scans taken when you entered the country may still be on file even if you opt out going forward.
Know Where the Added Risk Is
A few factors raise your exposure while traveling:
- Criminal history. Even an old DUI or a minor plea deal can create removability. Never accept a criminal plea of any kind without running it by your immigration attorney first.
- Certain states. Some states, including Texas, Alabama, and Florida, have laws that increase the odds a routine traffic stop turns into a detention or arrest. If you have any status concerns, get legal advice before traveling through these areas.
- Buses and trains near the border. Border Patrol can board buses and trains and question passengers without a warrant within 100 miles of any U.S. border — a zone that covers far more territory than most people realize, including large stretches of Texas, California, Arizona, Florida, Michigan, and New England.
If You’re Stopped, Questioned, or Detained
Stay calm — don’t run, argue, or resist physically. You are required to show your green card if asked, so present it. You can still decline a facial scan and ask for manual verification. You have the right to remain silent, and you can say so directly. You also have the right to ask for a lawyer — once you do, stop talking. And don’t sign anything, especially a Voluntary Departure form, without your attorney’s input; signing one permanently waives your right to a hearing before an immigration judge.
