Yes, green card holders are being detained by federal immigration authorities, and the pace picked up sharply in late 2025 and into 2026. Lawful permanent residents keep strong legal protections, but those protections have limits. A criminal conviction, a long absence from the United States, or a finding that you obtained your green card through fraud can each land you in an immigration detention facility. What follows is what triggers detention, what happens once you are in custody, and what defenses you still have.
Why Detentions of Permanent Residents Have Increased
Federal enforcement targeting green card holders escalated beginning in late 2025. The administration has publicly stated it is monitoring the criminal histories and social media activity of lawful permanent residents, and ICE has prioritized arrests of green card holders with past criminal convictions or allegations of political activity deemed problematic. Columbia University graduate Mahmoud Khalil, a green card holder, was detained in early 2025 based on allegations that he omitted information from his green card application. His case drew national attention and multiple federal court rulings.
The practical effect is that permanent residents with old misdemeanor convictions, minor application discrepancies, or lawful political activity have found themselves facing detention and removal proceedings. Green card holders returning from international travel have reported heightened scrutiny at airports and land crossings, and some are choosing to forgo travel entirely rather than risk an encounter with Customs and Border Protection.
Criminal Convictions That Trigger Detention
The most common reason a lawful permanent resident ends up in immigration custody is a criminal conviction. Federal law splits these cases into two tracks: mandatory detention, where the government has no choice but to hold you, and discretionary detention, where an officer or judge decides whether to hold you or let you go.
Mandatory Detention
Under federal immigration law, the government must take you into custody the moment you finish a criminal sentence if your conviction falls into certain categories. There is no bond hearing and almost no possibility of release while your case moves through immigration court.1Office of the Law Revision Counsel. 8 USC 1226 – Apprehension and Detention of Aliens A narrow exception exists when the Attorney General determines your release is necessary to protect a witness cooperating with a major criminal investigation, and even then you must show you are not a danger and will appear for hearings.2Congressional Research Service. Nielsen v Preap – High Court Clarifies Application of Immigration Detention Statute to Criminal Aliens
The convictions that trigger mandatory detention include:
- Aggravated felonies. This is a term of art in immigration law that covers far more than what most people think of as “aggravated.” A theft conviction with a sentence of one year or more qualifies, even if the court suspended the entire sentence. Fraud offenses where the victim lost more than $10,000 also count. The full list runs to over 20 categories, including drug trafficking, certain firearms offenses, and crimes of violence.3U.S. Citizenship and Immigration Services. USCIS Policy Manual – Permanent Bars to Good Moral Character4Legal Information Institute. 8 USC 1101(a)(43) – Aggravated Felony
- Controlled substance offenses. Any conviction related to a controlled substance, including simple possession of most drugs other than a small amount of marijuana for personal use, triggers mandatory detention.1Office of the Law Revision Counsel. 8 USC 1226 – Apprehension and Detention of Aliens
- Crimes involving moral turpitude. This category covers offenses that involve dishonesty, fraud, or conduct that shocks the conscience. Courts have interpreted this broadly to include forgery, tax evasion, domestic violence, and certain theft crimes.
- Firearms offenses. Buying, selling, or possessing firearms in violation of federal or state law.
The Supreme Court confirmed in Jennings v. Rodriguez that federal detention statutes do not require periodic bond hearings or impose a time limit on how long you can be held during removal proceedings.5Justia. Jennings v Rodriguez, 583 US (2018) Mandatory detention can last months or longer.
The Petty Offense Exception
Not every criminal conviction leads to detention. If your only conviction involved a crime where the maximum possible penalty was one year or less in jail, and you were actually sentenced to six months or less, you fall within a statutory exception that shields you from inadmissibility based on that conviction.6Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens The exception only works for a single offense and only for crimes involving moral turpitude, not for drug convictions or aggravated felonies. Criminal defense attorneys rarely raise it, which is why immigration lawyers recommend that any noncitizen facing criminal charges get separate immigration counsel before accepting a plea.
Detention at the Border and After Long Absences
The border is where green card holders are most vulnerable. When you arrive at an airport or land crossing, you go through an initial screening. If the officer spots a concern, you are moved to secondary inspection, a controlled area where you cannot leave until the process finishes.
A returning green card holder is not normally treated as someone applying for admission. You already have that status. But federal law identifies six situations where that presumption disappears and you are treated as a new arrival. The most common triggers are being absent from the country for more than 180 consecutive days and having committed a criminal offense covered by the inadmissibility grounds. If any of these apply, the officer can deny you entry and initiate removal proceedings, which may include holding you in a detention facility.
The 180-Day and One-Year Thresholds
If you have been outside the United States for more than 180 consecutive days, you lose the automatic presumption that you are simply returning home. You are processed like a new arrival and must show you remain eligible for admission. Absences longer than one year create a much stronger presumption that you abandoned your permanent resident status, and the burden shifts heavily to you to prove your intent to live in the United States never changed.
Officers look at concrete evidence: whether you filed federal tax returns, maintained a home, kept a bank account, or had family living in the country. If the evidence points toward abandonment, you can be placed in removal proceedings and detained while the case is resolved.
Reentry Permits
A reentry permit is the single best protection against abandonment findings during extended travel. You apply on Form I-131 while physically present in the United States, and if approved, the permit lets you stay abroad for up to two years without Customs and Border Protection treating the length of the absence alone as evidence of abandonment.7U.S. Citizenship and Immigration Services. Instructions for Form I-131, Application for Travel Documents If you have already spent more than four of the last five years outside the country, the permit’s validity drops to one year. A reentry permit does not guarantee readmission. Officers can still question your eligibility on other grounds.
Fraud or Misrepresentation on Your Original Application
Obtaining your green card through fraud or by misrepresenting a material fact makes you inadmissible, and discovery of such fraud can lead to arrest and removal proceedings regardless of how long ago it happened.8U.S. Department of State Foreign Affairs Manual. 9 FAM 302.9 – Ineligibility Based on Illegal Entry, Misrepresentation and Other Immigration Violations The most common examples are entering into a marriage solely to obtain a green card, concealing a criminal record on the application, and using fraudulent documents.
Because the government’s position is that the underlying basis for your status was defective from the start, fighting the case is harder than in other removal scenarios. Standard forms of relief, including cancellation of removal, are often unavailable because they require a valid period of lawful permanent residence. The Khalil case in 2025 showed how application omissions the applicant may not have considered material can become the government’s primary theory for detention and removal years later.
The First 48 Hours in Custody
Federal regulations require that within 48 hours of your arrest, ICE decide whether to continue holding you, release you on bond, or let you go on your own recognizance.9eCFR. 8 CFR 287.3 – Disposition of Cases When Arrested Without Warrant During that initial processing, ICE must also tell you why you were arrested, advise you of your right to an attorney at your own expense, and provide a list of free legal service providers in the area where your hearing will be held.
After that 48-hour window, your path splits depending on whether your case falls under mandatory or discretionary detention.
Bond Hearings
If you are not subject to mandatory detention, you can request a bond hearing before an immigration judge. The statutory minimum bond amount is $1,500, but judges routinely set bond much higher depending on your ties to the community, criminal history, and perceived flight risk.10Office of the Law Revision Counsel. 8 USC 1226 – Apprehension and Detention of Aliens At the hearing, the government attorney will present negative factors, including prior convictions and immigration violations. You can respond, present evidence of your community ties and employment, and argue that you are not a danger and will show up for future hearings. If ICE initially set a bond you cannot afford, the immigration judge has authority to lower it.
Bond hearings are typically scheduled a few weeks to a few months after you request one. You remain in detention in the meantime. If your case involves mandatory detention, you generally cannot get a bond hearing at all, though some federal courts have recognized due process limits on indefinite mandatory detention.
Your Right to a Lawyer
You have the right to hire an attorney for your immigration proceedings, but the government will not provide one or pay for one. Immigration court is a civil proceeding, not a criminal one, so the Sixth Amendment right to appointed counsel does not apply. The immigration judge will give you a list of organizations that offer free or low-cost legal services, but demand far exceeds supply. Most detained people who find representation do so through pro bono attorneys, nonprofit legal organizations, or family members who hire private counsel.
If you are detained at an airport or border crossing, you can ask to speak with a lawyer, but the government is not required to grant that request during the inspection process. Having an attorney’s phone number accessible before you travel internationally is worth the preparation.
Defenses Against Removal
Cancellation of Removal
If you are placed in removal proceedings but have lived in the country long enough with a clean enough record, cancellation of removal may be available as a defense. To qualify, you must have been a lawful permanent resident for at least five years, have lived continuously in the United States for at least seven years after being admitted in any status, and must not have been convicted of an aggravated felony.11Office of the Law Revision Counsel. 8 USC 1229b – Cancellation of Removal; Adjustment of Status
The aggravated felony bar is absolute. If your conviction qualifies as an aggravated felony under the immigration definition, cancellation of removal is off the table regardless of how long you have lived here or how strong your ties are. Even if you clear the eligibility requirements, the immigration judge still exercises discretion, weighing your length of residence, family ties, employment history, and the seriousness of the offense that triggered proceedings.
Challenging Prolonged Detention
If the government cannot actually deport you within a reasonable time, it cannot hold you indefinitely. The Supreme Court held in Zadvydas v. Davis that after a final removal order, six months of detention is presumptively reasonable. Once that period passes, if you can show there is no significant likelihood of your removal in the reasonably foreseeable future, the government must either justify continued detention or release you.12Legal Information Institute. Zadvydas v Davis, 533 US 678 (2001)
The mechanism is a habeas corpus petition filed in federal district court, separate from your immigration case and heard by a federal judge. Habeas petitions can challenge both post-removal detention under the Zadvydas framework and pre-removal mandatory detention that has stretched so long it arguably violates due process. Courts have increasingly recognized that even mandatory detention cannot be truly indefinite, though exactly where the constitutional line falls varies by circuit. Filing a habeas petition requires legal representation you can actually access, which is a real barrier for people held in remote facilities.
Alternatives to Physical Detention
Not everyone in removal proceedings sits in a detention facility. ICE operates an Alternatives to Detention program that allows eligible individuals to be released under supervision. Adults 18 and older who are in removal proceedings or subject to a final removal order may qualify.13Immigration and Customs Enforcement. Alternatives to Detention
Enrollment decisions turn on your criminal history, immigration record, family ties, caregiver status, and humanitarian or medical considerations. The most common supervision method is a GPS ankle monitor. Wearers face unannounced home visits, nightly curfews, and geographic restrictions on travel. Missing a check-in or tampering with the device can result in immediate re-detention. Availability has fluctuated with enforcement priorities, and during periods of expanded enforcement, ICE has favored physical detention over supervised release.
How to Reduce Your Risk
The difference between a green card holder who gets through a legal scare and one who ends up deported often comes down to preparation.
- Get immigration advice before any criminal plea. A misdemeanor plea that looks like a good deal in criminal court can be an aggravated felony under immigration law, and the consequences are effectively irreversible.
- Apply for a reentry permit before extended travel. If you will be outside the country for more than six months, file Form I-131 before you leave. You must be physically present in the United States when you file.7U.S. Citizenship and Immigration Services. Instructions for Form I-131, Application for Travel Documents
- Keep evidence of your ties to the United States. Tax returns, lease agreements, utility bills, bank statements, and records of your children’s school enrollment all help demonstrate that you intend to remain here permanently.
- Know what is on your record. Old convictions you may have forgotten about can surface during a border crossing or a USCIS interview. If you have any criminal history, consult an immigration attorney to understand whether it creates removal risk.
- Consider naturalization. Once you are a U.S. citizen, deportation is no longer possible. If you have been a permanent resident for at least five years (or three years if married to a U.S. citizen), meet the continuous residence and physical presence requirements, and have no disqualifying criminal convictions, citizenship removes the risk entirely.
Green card status is durable but not permanent in the way citizenship is. The enforcement environment in 2025 and 2026 has made that distinction concrete for thousands of families, and knowing the triggers, the process, and the defenses is the most practical protection you have.
