How to Get US Citizenship as an Indian Citizen

An Indian citizen becomes a U.S. citizen through naturalization: file Form N-400 after holding a green card for at least five years (or three years if you are married to and living with a U.S. citizen), pass a background check, interview, and English and civics tests, then take the Oath of Allegiance. The filing fee is $710 online or $760 by mail, and the full process usually takes six to ten months. Because India does not allow dual citizenship, getting U.S. citizenship as an Indian citizen means you must surrender your Indian passport afterward, though you can apply for an Overseas Citizenship of India (OCI) card to preserve most of your travel and property rights in India.

Who Qualifies to Naturalize

USCIS will approve your Form N-400 only if you meet every one of these requirements:

You are at least 18 when you file.
You have held a green card for at least five years, or at least three years if married to and living with a U.S. citizen.
You have maintained continuous residence in the United States throughout that period.
You have been physically present in the U.S. for at least 30 months of the five-year period, or 18 months of the three-year period.
You have good moral character.
You can read, write, and speak basic English and can pass a civics test on U.S. history and government.
You are willing to support and defend the U.S. Constitution.

These are the standard requirements for the five-year path.¹

How Trips to India Can Affect Your Case

This is the requirement Indian applicants trip over most often, because visits home to see family accumulate. A single trip of six months or less is generally fine. A trip of more than six months creates a legal presumption that you broke continuous residence, and you will have to produce evidence that your job, home, and family stayed in the United States during your absence.²

A trip of one year or longer automatically breaks continuous residence, and USCIS must deny your application unless you had preserved your residence in advance by filing Form N-470. There is no way to fix a one-year absence after the fact.²

Physical presence is a separate count. Even if no single trip was long enough to raise a flag, all your days abroad still add up against the 30-month (or 18-month) minimum.³

One boundary worth noting: male applicants who lived in the U.S. as permanent residents between ages 18 and 26 were required to register with the Selective Service within 30 days of turning 18. A knowing failure to register can be treated as evidence of poor moral character. If you never registered and are still under 26, do so at sss.gov before you file.⁴

Filing Form N-400

Form N-400 asks for your full immigration, marital, employment, and school history, and a record of every trip you have taken outside the United States since receiving your green card. Compile it carefully.⁵

Before you start the form, gather your green card, all current and expired passports (Indian and any others), your birth certificate, marriage or divorce certificates if relevant, and records of any criminal history, including minor traffic matters. For the travel section, dig out entry and exit dates for every visit to India, however short.

You can file up to 90 days before you hit the required residence anniversary. If your five-year mark falls on September 1, the earliest you can file is roughly June 3, and USCIS will hold the application until you reach the anniversary.⁶

Filing Channels and Fees

File online through a USCIS account for $710, or on paper by mail for $760. Biometrics are included in both figures. A reduced fee of $380 is available if your documented household income is at or below 400% of the Federal Poverty Guidelines, and a full fee waiver is available through Form I-912 for applicants who cannot pay. Current and former U.S. military members pay nothing.⁷⁸

If you hire an immigration attorney, legal fees for N-400 help typically run between $500 and $3,000 depending on complexity and location.

Filing online has practical advantages: electronic payment, case status tracking, notifications, evidence responses, and address updates in one place.⁸

Biometrics, the Interview, and the Tests

After USCIS accepts your application, you receive a receipt notice with a case number, then an appointment to give fingerprints, a photo, and a signature for background checks. Do not miss it. A missed biometrics appointment can lead USCIS to treat your application as abandoned.

You can still travel internationally while your N-400 is pending, because you are a permanent resident until the oath. The same absence rules keep applying: under six months is generally safe, six months to a year risks a presumption you broke continuous residence, and a year or more will almost certainly sink the case.²

At the Interview

A USCIS officer walks through your N-400 line by line, verifies your identity, asks about your background and travel, evaluates your good moral character, and administers the tests. Bring:⁹

Your interview appointment notice
Your green card
A state-issued photo ID such as a driver’s license
All passports and travel documents, valid and expired, issued since you became a permanent resident
Original supporting documents such as marriage certificates, divorce decrees, or court records where relevant

At the end, the officer tells you whether your case is approved, continued (more evidence needed, or you need to retake part of the test), or denied.

The English and Civics Tests

The English test has three parts. For reading, the officer shows up to three sentences and you pass by reading one correctly aloud. For writing, the officer dictates up to three sentences and you pass by writing one legibly. Speaking is evaluated through your conversation with the officer during the interview itself.¹⁰

For anyone filing N-400 on or after October 20, 2025, the civics test is the 2025 version: an oral exam of up to 20 questions drawn from a published list of 128. You need 12 correct to pass, and the officer stops once you reach 12 correct or 9 incorrect.¹¹ USCIS publishes the full question list and vocabulary lists for the English test free on its website.¹²

Older applicants get some relief. If you are 50 or older with 20 years as a permanent resident, or 55 or older with 15 years, you can skip the English requirement and take the civics test in your preferred language with an interpreter. If you are 65 or older with 20 years as a permanent resident, you also get a simplified civics test.¹³

The Oath and Your Certificate

If the officer approves your case, the final step is the Oath of Allegiance at a naturalization ceremony. Some field offices administer the oath the same day as the interview; others schedule a separate date.¹⁴

At the ceremony you return your green card and take the oath. You leave with a Certificate of Naturalization, which is your official proof of citizenship. Keep it safe. You will use it to get a U.S. passport, register to vote, and handle other civic matters. From that day on, use a valid U.S. passport for all international air travel.

Most applicants can expect roughly six to ten months from filing to oath, though timing varies by field office.

If USCIS Denies Your Application

You have 30 days from the denial notice to request a hearing by filing Form N-336. A different officer reviews the case. A late filing may be treated as a motion to reopen (if you have new evidence) or a motion to reconsider (if USCIS misapplied the law), but there is no guarantee a late request will be accepted.¹⁵

If USCIS upholds the denial, you can seek review in federal district court. Common reasons applications fail: missing the residence or physical presence thresholds, failing the English or civics test after two tries, undisclosed criminal history, or unresolved Selective Service problems.

Surrendering Your Indian Passport and Getting an OCI Card

India does not permit dual citizenship. Continuing to hold or travel on your Indian passport after you become a U.S. citizen is a criminal offense under Indian law that can carry penalties and imprisonment.¹⁶

After the oath, surrender your Indian passport to the nearest Indian consulate or VFS Global center for cancellation. The passport must be stamped “cancelled due to acquiring foreign nationality,” not just given a generic cancellation. You have up to three years from acquiring U.S. citizenship to finish the renunciation process. The fee is roughly $25 plus a $19 VFS service charge and a small Indian Community Welfare Fund contribution, with card-payment convenience charges on top. Once you start a VFS application, you have 20 calendar days to complete it, or it is returned unprocessed.¹⁷

Applying for the OCI Card

You cannot file for renunciation and OCI together. Finish the renunciation first, then apply for the OCI card separately.¹⁶

The OCI card is the closest thing to dual citizenship India offers. It gives you a multiple-entry, lifelong visa for visiting India for any purpose, exemption from foreigner registration no matter how long you stay, and domestic airfare pricing on par with Indian citizens. You can buy and sell residential and commercial property, though not agricultural land or farmhouses. OCI holders can also practice professions such as law, medicine, accounting, and architecture in India, and are eligible for teaching positions at major Indian universities.¹⁸

Some activities still require special permission: research, journalism, missionary work, and travel to restricted areas. OCI holders can sit for entrance exams like NEET and JEE, but only for Non-Resident Indian or supernumerary seats, not seats reserved for Indian citizens.¹⁸

What Happens to Your Children

Children under 18 who are already green card holders and living with you may become U.S. citizens automatically the moment you naturalize. Under the Child Citizenship Act of 2000, a foreign-born child acquires citizenship automatically when all of these are true:¹⁹

At least one parent is a U.S. citizen by birth or naturalization
The child is under 18
The child lives in the legal and physical custody of the U.S. citizen parent
The child has been admitted as a lawful permanent resident

Citizenship in this situation is automatic; no separate naturalization application is needed. To get proof of it, file Form N-600 (Application for Certificate of Citizenship). That certificate works the same as a naturalization certificate for getting your child a U.S. passport.²⁰

Children who were already 18 or older on February 27, 2001, when the law took effect, do not qualify. Adult children must file their own N-400 and go through naturalization on their own.¹⁹
