US citizenship through marriage: 7 requirements foreign spouses must meet before applying

Foreign nationals married to US citizens may qualify for a shorter path to American citizenship, but marriage alone does not make someone eligible for naturalisation. Applicants must meet specific age, residency, marital and character requirements before submitting their applications.

Under Section 319(a) of the Immigration and Nationality Act (INA), eligible spouses of US citizens can apply for naturalisation after three years as lawful permanent residents, rather than the usual five-year period available to many other green card holders.

The United States Citizenship and Immigration Services (USCIS) requires applicants to meet several conditions, including being at least 18 years old when filing Form N-400, the Application for Naturalisation.

What Is the Minimum Age to Apply for US Citizenship Through Marriage?

Foreign spouses must be at least 18 years old when they submit Form N-400 to apply for US citizenship through marriage.

The requirement applies even if the applicant married an American citizen before turning 18. Applicants must satisfy the age condition at the time of filing their naturalisation application.

Meeting the age requirement does not automatically guarantee approval. USCIS also assesses the applicant’s immigration history, marital relationship, physical presence in the United States and good moral character.

7 Requirements for US Citizenship Through Marriage

Foreign spouses applying under Section 319(a) must satisfy the following conditions.

1. Hold a Green Card for at Least Three Years

Applicants must have been lawful permanent residents of the United States for at least three years immediately before filing Form N-400.

This means that getting married to an American citizen does not immediately make a foreign national eligible for citizenship. The applicant must first obtain lawful permanent resident status and meet the required waiting period.

2. Remain Married to a US Citizen

Applicants must have lived in a genuine marital union with their US citizen spouse throughout the three years immediately before filing.

The spouse must also have been a US citizen during that period. The qualifying marital relationship must generally continue while USCIS processes the application and through the naturalisation process.

A marriage certificate alone does not establish that every requirement has been met. USCIS may assess evidence showing that the couple has maintained a genuine marriage.

3. Meet the Physical Presence Requirement

Applicants must have been physically present in the United States for at least 18 months out of the three years immediately preceding their application.

Time spent outside the country may affect eligibility, depending on the duration and circumstances of the absence.

Foreign spouses should keep records of their international travel and review their travel history before applying, particularly if they have spent extended periods outside the United States.

4. Live in Their State or USCIS District for at Least Three Months

Applicants must have lived for at least three months in the state or USCIS district where they claim residence before filing Form N-400.

Those who recently moved may need to wait until they satisfy this local residency condition.

5. Demonstrate Good Moral Character

USCIS requires applicants to demonstrate good moral character during the three years immediately preceding their application and through the Oath of Allegiance.

Immigration violations, certain criminal offences, fraud or other conduct may affect an applicant’s eligibility. The consequences depend on the circumstances and the applicable immigration rules.

Applicants should disclose relevant information accurately and seek qualified immigration advice if they have concerns about their records.

6. Show Attachment to the US Constitution

Applicants must demonstrate attachment to the principles of the US Constitution and a willingness to uphold the good order and happiness of the United States.

This forms part of the broader naturalisation requirements and is assessed alongside other eligibility conditions.

7. Complete the Naturalisation Process

Eligible applicants must submit Form N-400 and complete the applicable USCIS procedures.

Depending on the case, this may include a biometrics appointment, a naturalisation interview, English-language and civics requirements, and taking the Oath of Allegiance after approval.

Applicants should check the current USCIS instructions to determine the documents, fees and procedures that apply to their individual circumstances.

Can Foreign Spouses Apply After Three Years Without a Green Card?

No. The three-year naturalisation route is not a substitute for obtaining permanent residence.

Applicants generally must first secure a green card through an eligible immigration process. They must then complete the required three years as lawful permanent residents while meeting the marriage and other naturalisation conditions.

A person who has been married to a US citizen for three years but has not held permanent resident status for the required period does not qualify under this provision on the basis of marriage alone.

Does Every Spouse of a US Citizen Qualify for the Three-Year Rule?

No. Applicants must satisfy all the applicable requirements, not simply be married to an American citizen.

The three-year route under Section 319(a) has specific conditions concerning permanent residence, the duration of the marital union, physical presence and good moral character.

US immigration law also contains separate provisions for certain spouses of US citizens serving in the military or working abroad. These cases may involve different eligibility rules, so applicants should consult the relevant USCIS guidance rather than assume the standard three-year requirements apply unchanged.
