You’d think being a U.S. citizen is the ultimate "get out of jail free" card when it comes to immigration. It’s the finish line. The gold standard. But honestly, the system is a lot messier than the brochures make it look. People often ask, "how many legal citizens have been deported?" and they expect a simple number.
The truth? It’s not simple. It’s actually kind of terrifying.
The government doesn't keep a neat little spreadsheet labeled "Citizens We Accidentally Kicked Out." Instead, we have to look at data from groups like the Deportation Research Clinic at Northwestern University and the Cato Institute. These researchers have spent years digging through messy court records and ICE logs to find the people who should never have been in the system to begin with.
The Reality of How Many Legal Citizens Have Been Deported
Let’s get into the weeds. While the Department of Homeland Security (DHS) officially says they don't deport citizens, the records tell a different story.
According to research led by Jacqueline Stevens at Northwestern, thousands of U.S. citizens are detained or even deported every year. It sounds like a conspiracy theory until you see the case files. Stevens' research suggests that in some years, up to 1% of people in immigration detention are actually U.S. citizens.
Wait. One percent?

That might sound small. It’s not. If you have 65,000 people in detention—which was the case around late 2025—that’s potentially hundreds of Americans sitting in a cell waiting to prove they belong here. In fact, ProPublica found that during the first nine months of 2025 alone, more than 170 U.S. citizens were held by immigration agents. Some were kids. Two had cancer. It’s a bureaucratic nightmare that doesn't care about your passport.
Why does this keep happening?
It usually boils down to bad paperwork and "papers-please" profiling.
- Outdated Databases: The systems ICE uses aren't always synced. If you naturalized recently, the system might still flag you as a "non-citizen."
- Derivative Citizenship: This is a big one. If you became a citizen because your parents naturalized while you were a minor, proving it is a legal headache. Most people don't carry their parents' 20-year-old naturalization certificates in their back pockets.
- Mental Health Issues: People with cognitive disabilities sometimes struggle to explain their status or provide the right documents during a high-stress raid.
- Lack of Counsel: Unlike in criminal court, you don't get a free lawyer in immigration court. If you can't afford one, you're on your own against a federal prosecutor.
Basically, if the computer says you're not a citizen, the agents often believe the computer over the person standing in front of them.
The 2025-2026 Surge and "Foreign Policy Grounds"
The landscape changed significantly in 2025. With a massive push for deportations, the margin for error got even thinner.
We saw a new trend: the use of "foreign policy grounds" to target people. Take the case of Mahmoud Khalil. He was a Palestinian graduate with a green card—a legal permanent resident. In early 2025, he was arrested. Even though his wife showed agents his green card, they claimed it had been revoked under a rarely used provision because of his political activism.

While Khalil isn't a "citizen" by birth, his case highlights how quickly "legal" status can evaporate. When the government starts using speech or viewpoint as a reason to deport, the line between "legal resident" and "removable alien" gets very blurry, very fast.
Recent Stats (As of January 2026)
By the end of 2025, reports indicated that over 622,000 people had been deported in a single year. While the vast majority are non-citizens, the sheer volume of "expedited removals"—where you don't even see a judge—increases the risk for citizens.
The Cato Institute recently flagged that ICE arrests of people with no criminal convictions rose by a staggering 1,200%. When you're casting a net that wide, you're going to catch some "wrong" fish.
In some cases, people are "self-deporting" out of fear. About 1.9 million people left the U.S. on their own in 2025. How many of those were citizens who just didn't want to deal with the risk of being detained indefinitely? We may never know.
What You Can Actually Do
If you're a naturalized citizen or have "derivative" citizenship, the "it can't happen to me" mindset is risky. It’s better to be prepared for a system that sometimes glitches.

1. Digital Backups are King
Don’t just have your passport. Have a high-res scan of your naturalization certificate or your U.S. birth certificate on a secure cloud drive. If you’re a derivative citizen, keep copies of your parents’ papers too.
2. Know the "Right to Remain Silent"
This applies even in immigration encounters. You don't have to answer questions about where you were born or how you entered the country without a lawyer. Honestly, talking your way out of it often makes it worse if you get a detail wrong.
3. The "G-28" Form
If you have a lawyer, keep their contact info and a signed G-28 (Notice of Entry of Appearance) handy. It’s a formal way to tell ICE, "Talk to my attorney, not me."
4. Check Your Records
If you’ve had any run-ins with the law or immigration in the past, it might be worth doing a FOIA (Freedom of Information Act) request for your own "A-File." See what the government has on you. If there’s an error, fix it now, not when there’s a knock at the door.
The system isn't perfect. It’s a massive machine, and sometimes it grinds up the very people it’s supposed to protect. Knowing the numbers is the first step toward making sure you don't become one of them.
