The US Citizenship and Immigration Services (USCIS) has published eligibility requirements showing how foreign nationals married to American citizens can qualify for citizenship in three years, instead of the standard five-year residency period. The faster route applies only to lawful permanent residents who are living in a valid marriage with a US citizen spouse throughout the application period.
Who Qualifies for the 3-Year Naturalization Route?
To use this faster pathway, an applicant must be at least 18 years old at the time of filing Form N-400, the Application for Naturalisation. They must have held a green card for a minimum of three years immediately before submitting the form, and must have lived in a genuine marital union with their US citizen spouse throughout that same three-year period, as well as during the time USCIS is processing the application.
Physical presence inside the US is also a hard requirement. Applicants must have been physically present in the country for at least 18 of the 36 months before filing, and must have lived for no fewer than three months in the state or USCIS district that covers their place of residence. According to USCIS, continuous residence from the date of filing until the point of naturalisation is mandatory, meaning extended absences abroad during the application process could disrupt eligibility.
Language, Civics, and Character Requirements
Beyond residency conditions, applicants must demonstrate the ability to read, write, and speak English. They are also required to pass a civics test covering the history, principles, and system of government of the United States. USCIS further requires that applicants show good moral character for the full three years before filing and up to the point they take the Oath of Allegiance. This includes being attached to the principles of the US Constitution and supporting the good order of the country.
For most permanent residents who are not married to US citizens, the standard naturalisation route requires five years of lawful permanent residence, making the spousal pathway a significant advantage for eligible individuals. The legal basis for this accelerated process is section 319(a) of the Immigration and Nationality Act (INA), which specifically addresses the reduced residency timeline for spouses of US citizens.
Related Citizenship Waivers and Procedures
In a related story, Legit.ng reported that the US had revealed the oath that foreigners must take before finally becoming citizens of America. Meanwhile, Legit.ng previously reported that the US had published the categories of foreigners who can become citizens without an oath ceremony. Under standard procedure, when an officer approves a Form N-600 application, USCIS administers the Oath of Allegiance before issuing the certificate. However, the INA gives USCIS the authority to waive the oath for individuals it determines cannot understand its meaning.
These provisions highlight the various pathways available for eligible foreign nationals seeking US citizenship, with the three-year spousal route offering a faster alternative to the standard five-year wait for those who meet all the conditions.
