Qualifying family relationships — mainly marriage to a US citizen or permanent resident, and other legally defined family relationships — are one of the most common Green Card paths. The process requires proving the relationship's legitimacy and going through USCIS review; it's not automatic simply from the marriage or family relationship itself.

Family-based Green Card paths

Generally, spouses, children, parents and siblings of US citizens, and spouses and children of permanent residents, may qualify for a Green Card through a family relationship, via a petition filed by the qualifying relative in the US. Timelines and priority vary significantly by degree of relationship and category — spouses, parents and unmarried children under 21 of US citizens tend to have shorter timelines than other family categories.

Green Card through marriage

After marriage, the foreign spouse can apply for a Green Card through a family petition, followed by adjustment of status (if already in the US) or consular processing (if outside the country). USCIS reviews evidence of the relationship's legitimacy — joint financial documents, history of living together, photos, among others — and may conduct an interview with the couple.

Fiancé(e) visa — K-1

The K-1 is for engaged couples, where one of the two is a US citizen, who intend to marry in the United States. It allows the foreign fiancé(e) to enter the country, requires the marriage to happen within 90 days of entry, and after the marriage, the spouse can apply for adjustment of status to a Green Card.

Adjustment of status vs. consular processing

Adjustment of status is the process for someone already physically in the United States (in valid status) to apply for a Green Card without leaving the country. Consular processing is the equivalent path for someone outside the US, done through a US consulate or embassy. The choice between the two depends on where the person is and their current immigration situation — it's not a free choice in every case.

Frequently asked questions

Does marrying a US citizen automatically guarantee a Green Card?
No. Marrying a US citizen allows you to apply for a Green Card through a family relationship, but the process requires proving the relationship is genuine, plus review by USCIS (and, in many cases, an interview). Marriages found to be fraudulent, entered into solely to obtain an immigration benefit, are investigated and can result in denial and other consequences.
What's the difference between the K-1 visa and a direct marriage-based Green Card?
The K-1 is a fiancé(e) visa: it allows the person to enter the US to marry within 90 days, and after the marriage, to apply for adjustment of status to a Green Card. A direct marriage-based Green Card applies to those already married — the process can be done through adjustment of status (if already in the US) or consular processing (if outside the country).
What's the difference between adjustment of status and consular processing?
Adjustment of status is the process for someone already physically in the United States to apply for a Green Card without leaving the country. Consular processing is the path for someone outside the US, done through a US consulate or embassy abroad.
