Yes — most of the Bill of Rights applies to non-citizens living in the United States, because the Constitution repeatedly limits what the government can do to “persons,” not just “citizens.” Due process, free speech, protection from unreasonable searches, and the right to a fair criminal trial cover everyone on U.S. soil regardless of immigration status. A few rights, though, are reserved for citizens alone, and some protections weaken sharply at the border.
Why the Constitution Protects “Persons”
The framers picked their words carefully. When they meant to limit a right to citizens, they said “citizens.” When they meant everyone, they said “persons,” “people,” or “the accused.” The Fourteenth Amendment says no state shall deprive “any person” of life, liberty, or property without due process, or deny “any person” equal protection of the laws.1LII / Legal Information Institute. 14th Amendment The Fifth Amendment uses the same word to protect every person from self-incrimination and from losing life, liberty, or property without due process.2Cornell Law School. Fifth Amendment
The Supreme Court settled this reading in 1886. In Yick Wo v. Hopkins, the Court held that Fourteenth Amendment protections “extend to all persons within the territorial jurisdiction of the United States, without regard to differences of race, of color, or of nationality.”3Justia U.S. Supreme Court Center. Yick Wo v. Hopkins, 118 U.S. 356 (1886) That principle has held ever since.
One qualifier matters. In United States v. Verdugo-Urquidez, the Court suggested that rights belonging to “the people” (as the Fourth Amendment phrases it) may require a “sufficient connection” with the country — someone who has never entered the United States has weaker protections than someone living here.4Justia U.S. Supreme Court Center. United States v. Verdugo-Urquidez, 494 U.S. 259 (1990)
Due Process and Equal Protection
The Fifth and Fourteenth Amendments prevent any government, federal or state, from taking your freedom or property without fair procedures. For non-citizens, this means you cannot be detained or removed without a hearing. You are entitled to appear before an immigration judge, present evidence, and argue your case.
Due process also limits detention length. In Zadvydas v. Davis, the Supreme Court ruled that the government cannot detain a non-citizen indefinitely after a removal order when no country will accept them. The Court set a presumptive six-month limit; after that, if you can show there is no realistic chance of removal in the foreseeable future, the government must justify continuing to hold you.5Justia U.S. Supreme Court Center. Zadvydas v. Davis, 533 U.S. 678 (2001)
Federal law does require mandatory detention without bond for non-citizens convicted of certain serious offenses, including aggravated felonies, drug crimes, firearms violations, and some terrorism-related grounds. Once you fall into one of those categories, the government must take you into custody when you leave criminal incarceration, and a judge generally cannot set bail.6Office of the Law Revision Counsel. 8 USC 1226 – Apprehension and Detention of Aliens
Equal protection stops states from treating non-citizens as a permanent underclass. When a state law singles out non-citizens for worse treatment, courts apply heightened scrutiny. The Supreme Court used this principle in Plyler v. Doe to strike down a Texas law that barred undocumented children from public schools.7Justia U.S. Supreme Court Center. Plyler v. Doe, 457 U.S. 202 (1982) Congress has broader authority over immigration and federal benefits, and courts give federal immigration classifications more deference than state-level discrimination.
Free Speech and Religion
The First Amendment covers non-citizens living in the country. You can attend protests, publish criticism of the government, join a union, practice your faith, and open a place of worship. In Bridges v. Wixon, the Supreme Court reversed the deportation of a labor activist and held that “freedom of speech and of the press is accorded aliens residing in this country.”8Justia U.S. Supreme Court Center. Bridges v. Wixon, 326 U.S. 135 (1945) The word “residing” matters — non-citizens seeking entry for the first time have weaker speech protections, since no one has a constitutional right to enter the country.
Political money is the sharp exception. Federal law bars foreign nationals from making any contribution or expenditure connected to a federal, state, or local election, including donations to candidates and parties and spending on election ads. Violations can carry criminal penalties.9Office of the Law Revision Counsel. 52 USC 30121 – Contributions and Donations by Foreign Nationals Lawful permanent residents are exempt; everyone else, including people on work or student visas, is covered by the ban.
Search and Seizure
The Fourth Amendment protects “the people” from unreasonable searches and seizures. Police generally need a warrant based on probable cause to search your home or take your property, and you cannot be stopped and searched just because an officer thinks you might be an immigrant. There must be reasonable suspicion of criminal activity.10Congress.gov. Fourth Amendment – Searches and Seizures
The 100-Mile Border Zone
Fourth Amendment protections weaken near the border. Federal law lets Border Patrol operate within 100 air miles of any external U.S. boundary, a zone that includes roughly two-thirds of the country’s population. Within it, agents can board and search vehicles, trains, and aircraft for immigration violations without a warrant, and they can set up highway checkpoints to ask about citizenship.11U.S. Customs and Border Protection. Legal Authority for the Border Patrol
Even inside this zone, a full search of your vehicle or belongings still requires probable cause or your voluntary consent. At actual ports of entry — airports and land crossings — customs officers can inspect luggage with no suspicion at all. Rules for phones and laptops vary by federal circuit; some appeals courts require reasonable suspicion before a forensic copy, others do not. The Supreme Court has not settled the question.
ICE Warrants at Your Door
If ICE comes to your home, the type of warrant matters. A judicial warrant is signed by a judge after review of the evidence, and it is the kind of warrant the Fourth Amendment contemplates. An ICE administrative warrant, such as Form I-205, is signed by an immigration supervisor, not a judge. Lower courts have accepted administrative warrants for public immigration arrests but have not approved using them to force entry into a home. If an agent shows only an administrative warrant, you are generally not required to open the door.
Rights If You Are Charged With a Crime
If you are charged with a crime in the United States, you have the same trial protections as any citizen. The Sixth Amendment guarantees every accused person a speedy and public trial before an impartial jury, notice of the charges, the right to confront witnesses, and the right to call witnesses in your defense.12Congress.gov. Sixth Amendment If you face potential jail time and cannot afford a lawyer, one must be appointed for you under Gideon v. Wainwright. If you do not speak English fluently, federal courts must provide an interpreter.13Office of the Law Revision Counsel. 28 USC 1827 – Interpreters in Courts of the United States
The Eighth Amendment also applies, prohibiting excessive bail, excessive fines, and cruel and unusual punishment.14Congress.gov. Eighth Amendment
Guilty Pleas and Deportation
Non-citizens carry a risk citizens do not: a conviction can trigger removal. The Supreme Court held in Padilla v. Kentucky that defense attorneys have a constitutional duty to advise non-citizen clients about the immigration consequences of a guilty plea.15Justia U.S. Supreme Court Center. Padilla v. Kentucky, 559 U.S. 356 (2010) When the law clearly makes deportation automatic for a particular offense, your lawyer must tell you. When the risk is less certain, your lawyer must at least warn you that charges could carry immigration consequences. Failure to give this advice can be grounds to challenge the conviction for ineffective assistance of counsel.
No Free Lawyer in Immigration Court
The biggest gap in non-citizen rights sits in immigration court. Because deportation is classified as a civil matter rather than a criminal punishment, the Sixth Amendment right to appointed counsel does not apply. Federal law gives you the right to hire a lawyer for a removal hearing but explicitly says the government does not have to pay for one.16Office of the Law Revision Counsel. 8 USC 1362 – Right to Counsel
In practice, many people go through removal proceedings — where they can lose the right to live in the country — without any legal representation. A narrow federal program provides attorneys to detained individuals found mentally incompetent to represent themselves, but it does not cover the general population in removal proceedings. Courts have not recognized a broad constitutional right to appointed counsel in immigration cases.
Firearms and the Second Amendment
Federal law bars two groups of non-citizens from possessing firearms: anyone unlawfully present in the United States, and most people admitted on a nonimmigrant visa (tourist, student, or temporary worker visas, for example).17Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Lawful permanent residents are not subject to this ban and may buy and own firearms on the same terms as citizens.
Whether the Second Amendment protects non-citizens at all is unsettled. Federal appeals courts are split. In a December 2025 ruling, the Sixth Circuit held in United States v. Escobar-Temal that the Second Amendment’s “the people” can include undocumented individuals with substantial ties to the country, though it upheld the defendant’s conviction, finding historical tradition supports restricting firearm access for people unlawfully present.18United States Court of Appeals for the Sixth Circuit. United States v. Escobar-Temal The Fourth, Fifth, and Eighth Circuits have ruled that undocumented individuals are not part of “the people” at all. The Supreme Court has not resolved the split.
Rights Reserved for Citizens
Some rights are tied to citizenship, and non-citizens are excluded no matter how long they have lived in the country.p>
Voting
The Fifteenth, Nineteenth, and Twenty-Sixth Amendments protect the right of “citizens” to vote. Federal law makes it a crime for any non-citizen to vote for President, Vice President, or members of Congress, punishable by up to one year in prison, a fine, or both.19Office of the Law Revision Counsel. 18 USC 611 – Voting by Aliens A handful of municipalities in a few states allow non-citizens to vote in certain local elections such as school board races, but no state permits it in statewide or federal elections.
Federal Office
Members of the House must be U.S. citizens for at least seven years, senators for at least nine.20LII / Legal Information Institute. Overview of House Qualifications Clause The presidency requires natural-born citizenship. Non-citizens cannot hold any of these offices.
Jury Service
Federal jury service requires U.S. citizenship. Jurors must also be at least 18, able to communicate in English, and free of disqualifying felony convictions.21United States Courts. Juror Qualifications, Exemptions and Excuses State courts impose the same citizenship requirement for both criminal and civil juries.
