How to obtain USA citizenship in 2026 — naturalisation, marriage & descent

USA citizenship offers the highest status in the country, granting full rights, a U.S. passport and participation in civic life. In 2026, applicants may qualify by naturalisation after permanent residence, through marriage to a U.S. citizen, descent from parents, birth on U.S. soil, adoption, military service or other limited grounds. This guide explains categories, timelines, documents and integration requirements. If you are still on your first visa, review our USA visa guide to map your full immigration strategy.

Key terms

Citizenship by naturalisation: acquiring U.S. citizenship after meeting residence, English/civics and good-moral-character requirements.

USCIS (U.S. Citizenship and Immigration Services): federal agency that processes N-400 applications and conducts interviews and tests.

Form N-400: the application used to apply for naturalisation with USCIS.

Oath of Allegiance: the final ceremony at which citizenship is conferred and a certificate of naturalisation is issued.

Dual citizenship: the United States permits dual nationality in many cases; recognition by the other country may differ.

Continuous residence: the requirement to maintain an unbroken period of U.S. residence before applying for naturalisation.

Physical presence: the minimum number of days an applicant must have spent physically inside the United States within the qualifying period.

Good moral character: a statutory standard assessing conduct (e.g., taxes, criminal history) during the required residence period.

Civics and English tests: examinations of U.S. history/government knowledge and basic English reading, writing and speaking.

CRBA (Consular Report of Birth Abroad): a document proving U.S. citizenship for a child born outside the U.S. to qualifying U.S. parent(s).

Selective Service: registration requirement for certain male applicants that can affect eligibility for naturalisation.

Citizenship types

In 2026, lawful routes to citizenship include:

• Naturalisation: permanent residents may apply after 5 years, or after 3 years if married to a U.S. citizen.
• Marriage: naturalisation accelerated to 3 years for spouses of citizens living in marital union.
• Descent (by blood): children born abroad to U.S. parents may claim citizenship through CRBA or derived at birth if conditions met.
• Birth in the USA: jus soli — almost all born on U.S. soil are citizens regardless of parental status.
• Adoption: children adopted abroad by U.S. citizens may gain automatic citizenship under the Child Citizenship Act.
• Military service: non-citizens serving honorably may naturalise with waived residence years.
• Investment: no direct citizenship-by-investment program; investors usually naturalise via residence first.
• Humanitarian grounds: rare discretionary grants by Congress or executive authority.

Routes & timelines

Step-by-step

1. Confirm eligibility: check residence duration, marriage union, descent or service record.
2. File Form N-400: complete application with fees and supporting evidence.
3. Biometrics appointment: fingerprints for FBI background checks.
4. Interview: officer tests civics and English, reviews records, clarifies absences and moral character.
5. Decision: approval leads to oath ceremony scheduling; denial may be appealed.
6. Oath of Allegiance: final step granting certificate of naturalisation.

Documents

Applicants provide Green Card, passports, birth/marriage certificates, selective service proof, tax returns and residence evidence. Children deriving citizenship need CRBA. Civil documents in other languages must include certified translations; use trusted services to prevent delays.

Costs

The N-400 fee plus biometrics remains the main cost. Other expenses include translations, legal support, test preparation and travel. Fee waivers apply for low-income applicants. For global context, review our Residency & Citizenship hub.

Integration

Applicants must pass civics and English exams unless exempt by age or disability. Civics covers history and government; English tests require basic reading, writing and speaking. Exemptions: age 50/20 rule, age 55/15 rule, or medical disability. Continuous residence and good moral character remain essential.

What changed in 2026

Recent changes include redesigned digital N-400 filing, expanded civics test materials, pilot remote oath ceremonies, and clearer rules for derivative children. Processing times remain long but USCIS offers improved case-tracking tools.

Did you know?

Military naturalisation has waived residence for tens of thousands since World War II, making it one of the fastest citizenship routes ever created.

Common mistakes

• Applying before completing residence requirement.
• Failing to disclose long absences breaking continuous residence.
• Not registering for selective service when required.
• Poor preparation for English/civics test.
• Submitting uncertified translations of key records.
