US citizenship by marriage allows foreign spouses of American citizens to apply for naturalization after just three years of permanent residency, instead of the usual five.
The process requires first obtaining a marriage-based green card, maintaining three years of residence in marital union, and then applying for naturalization under USCIS rules.

- The naturalization application (Form N-400) fee is $760 (for paper filing) under current USCIS policy.

What are the benefits of marrying a US citizen?

What are the benefits of getting US citizenship?
US citizenship provides significant long-term advantages:
- Right to vote in federal, state, and local elections
- US passport and consular protection worldwide
- Eligibility for federal jobs and benefits not open to green card holders
- Ability to petition for more family members to immigrate
- No need to renew residency or fear of losing status after long absences
Are there any disadvantages of being a US citizen?

While the pros are substantial, some cons of US citizenship include:
- Worldwide taxation for US citizens – They must report global income, regardless of where they live.
- Jury duty and civic obligations – Participation in civic responsibilities is mandatory.
- Citizenship renunciation complexities – Giving up US citizenship later is difficult and costly.
How long can I stay in the US if I marry a US citizen?
A foreign spouse can live in the US indefinitely if they maintain lawful permanent residency, but the first marriage green card is conditional and valid for 2 years if the marriage is under two years old at approval.
After filing Form I-751 to remove conditions, the spouse receives a 10-year green card, which can be renewed indefinitely and eventually leads to eligibility for citizenship.
Can I work immediately after getting married to a US citizen?
Not automatically. Marriage alone does not give work rights in the United States. A foreign spouse must first apply for and receive work authorization.
This is usually granted with a pending green card application (via Employment Authorization Document, EAD) or upon approval of the green card itself.
How long does it take to bring a spouse to the USA with citizenship?
A US citizen can usually bring a foreign spouse to the United States within 8 to 24 months.
- Inside the US (Adjustment of Status): Processing of Form I-485 typically takes about 8–14 months.
- Outside the US (Consular Processing): The I-130 petition, NVC stage, and consular interview often take 12–24 months, though some cases finish closer to 10–14 months.
US Passport Ranking
The US consistently ranks among the world’s strongest passports.
- Henley Passport Index: Ranked 12th globally with access to 180 destinations.
- Arton Capital Passport Index: Places the US in 9th position for global mobility.
- Nomad Passport Index: US ranks lower due to tax burdens but still scores high for global mobility. It’s currently ranked at 45th.
Can an American get dual citizenship through marriage?
Yes. US citizens can generally acquire a second nationality by marrying a foreign national without losing their US citizenship.
The United States allows dual citizenship, meaning you do not have to renounce your American citizenship when obtaining your spouse’s nationality.
However, each country has its own rules regarding dual citizenship, so it’s important to check whether the spouse’s country permits retaining your original nationality.
Some countries may require naturalization applicants to renounce prior citizenship, which could affect the dual status.
Conclusion
United States citizenship by marriage remains one of the most efficient ways for foreign nationals to achieve permanent residency and eventually naturalization.
While the process involves careful documentation, fees, and waiting periods, the pathway is clear: green card through marriage, three years of residency, and then eligibility for naturalization.
For many couples, this route not only secures family unity but also unlocks the broader rights and opportunities of American citizens.
