Can You Become a U.S. Citizen? Yes — Here’s How

A taxi driver in Queens once asked me whether he could finally get the paper. He meant the passport, not the green card. He had been a lawful permanent resident for eleven years, filed taxes every April, and genuinely believed citizenship was something you were either born with or quietly denied. That is the most common gap I run into: people assume the door is locked when it is really just heavy, with a doorman who wants specific documents in a specific order.

So let us answer it plainly. Yes — you can become a U.S. citizen. Roughly a million people do it every year. But can you depends entirely on which of four lanes you happen to be standing in, and exactly one of those lanes has a queue.

• There are four routes to U.S. citizenship: birth on U.S. soil, citizenship through parents, naturalization, and rare special acts of Congress.
• Naturalization generally requires you to be 18 or older, hold a green card for five years (three if married to a citizen), show good moral character, and pass the English and civics tests.
• Marriage to a citizen does not hand you a passport. It shortens the clock, it does not skip the line.
• The United States permits dual citizenship, even though the Oath of Allegiance contains a renunciation clause.
• Most delays come from paperwork gaps, not from disqualifying facts.

Four Doors, and Only One Has a Line

Before you hire anyone or download a single form, figure out which door is yours. Getting this wrong wastes months, sometimes years.

The Two Routes You Never Apply For

Birthright citizenship is the loudest one. Under the Fourteenth Amendment, if you are born in the United States, you are a citizen — full stop, with a handful of exceptions that mostly involve children of foreign diplomats with immunity. American Samoa sits in its own odd category: people born there are U.S. nationals, not citizens, and can apply for citizenship if they choose. That distinction surprises almost everyone.

The second quiet route is citizenship through parents. It splits into two very different situations. Acquisition applies to someone born abroad to a citizen parent who met the physical presence rules — typically five years in the U.S., at least two of them after turning 14, though the math changes for unmarried mothers and unmarried fathers. Derivation is cleaner: under the Child Citizenship Act of 2000, a child under 18 who holds a green card and lives in the legal and physical custody of at least one U.S. citizen parent becomes a citizen automatically, by operation of law. No application, no fee, no oath. You still want the Certificate of Citizenship (Form N-600) as proof, because a passport alone will not always convince a skeptical clerk thirty years later.

Naturalization: Five Boxes, No Shortcuts

This is the path most people mean when they ask the question. It is also the one where preparation decides everything.

Time on the ground

You need five years as a permanent resident, or three years if you have been married to a U.S. citizen and living with them the whole time. Two subtleties trip people up constantly. First, continuous residence — a trip abroad of six months or more raises questions, and a year or more is presumed to break your residence unless you can rebut it. Second, physical presence — you must actually have been in the country for at least 30 months of those five years, or 18 months of the three-year window. You also need to have lived in the state or USCIS district where you file for at least three months.

Character they can verify

Good moral character is a five-year review (three in marriage cases). It is less about being a saint and more about the record. Certain offenses — murder, aggravated felonies — bar you permanently. Others bar you only inside the review window. Outside the criminal side, officers look at filed tax returns, child support, Selective Service registration if you are male and were in the country between 18 and 26, and whether you ever falsely claimed to be a citizen. That last one is a hard stop, so never tick that box casually on any form.

The English and civics tests

You will read, write, and speak basic English, then answer up to ten civics questions from a list of 100 and get six right. There are age and time exemptions: if you are 50 or older with 20 years as a permanent resident, or 55 or older with 15 years, you can take the civics test in your own language. At 65 with 20 years, you get a shorter, starred version of the test. A documented disability can waive the tests entirely through Form N-648.

What the Process Actually Feels Like

You file Form N-400 — around $710 online or $760 on paper, biometrics included under current fees. Then you wait for a fingerprint appointment, then an interview where an officer walks through your entire application line by line. Decisions come the same day more often than not. If approved, you are scheduled for a ceremony, sometimes within weeks, sometimes a few months if you want a judicial ceremony. At the ceremony you take the Oath of Allegiance and hand back your green card. The whole thing typically runs 8 to 14 months, though busy field offices stretch longer.

Two Passports in One Pocket

Here is the part that worries people unnecessarily. The Oath includes a renunciation of prior allegiances, but the United States does not require you to give up your other nationality, and it does not enforce the clause in ordinary cases. Millions of Americans hold a second passport. What matters is the other country’s rules — some allow dual nationality freely, some treat your naturalization as an automatic loss of theirs, and a few require you to notify them. Check that side of the ledger before the ceremony, not after.

Small Things That Quietly Sink a Case

• Failing to file Form AR-11 every time you move. Address history is checked.
• Filing before you have the full five or three years, hoping the officer will not count.
• Missing tax transcripts for a year you thought did not matter.
• Name spellings that differ between your green card, passport, and birth certificate with no documentation explaining why.
• Leaving Selective Service registration unaddressed if you were required to register.
• Treating a criminal citation as nothing. Even a dismissed charge needs the disposition paperwork.

What Actually Changes the Day After

You can vote. You can get a passport, usually within weeks. You can petition for your parents and adult children, and later for brothers and sisters, though sibling petitions take decades for most countries. You cannot be deported for the ordinary reasons that apply to green card holders. You can hold federal jobs that require citizenship and run for most offices. What does not change: worldwide tax obligations, jury duty summonses, and the fact that citizenship obtained through fraud can be revoked. It is a genuine ending and a genuine beginning at once.
