For foreign nationals married to U.S. citizens or lawful permanent residents, marriage-based immigration offers one of the most direct paths to permanent residency in the United States. A Marriage Green Card grants the foreign spouse the right to live and work permanently in the United States, travel freely in and out of the country, and eventually pursue U.S. citizenship. It is also one of the most closely scrutinized immigration pathways — USCIS reviews each application carefully to confirm the marriage is genuine. Understanding the requirements, process, and timeline before filing helps couples prepare a strong application and avoid common delays.

Who qualifies

Marriage-based Green Cards are available to foreign nationals who are legally married to a U.S. citizen or a lawful permanent resident. The nature of the sponsor’s status affects both the timeline and the category under which the petition is filed.

Spouses of U.S. citizens are classified as immediate relatives under U.S. immigration law — a designation that carries no annual numerical cap on available Green Cards. This means eligible applicants can generally proceed without waiting for a visa number to become available, making the process considerably faster than other family-based categories.

Spouses of Green Card holders fall under the family preference category F2A, which is subject to annual visa limits set by Congress. Applicants in this category must wait for their priority date — the date USCIS received the Form I-130 petition — to become current on the USCIS Visa Bulletin before proceeding with the final steps of the application.

To be eligible, the sponsoring spouse must be at least 18 years old and reside in the United States. The marriage must be legally valid under the laws of the country or state where it took place, and prior marriages must have been legally terminated through divorce, annulment, or death.

The bona fide marriage requirement

The central evidentiary requirement in any marriage-based Green Card application is demonstrating that the marriage is bona fide — entered into genuinely, not solely for immigration purposes. Marriage fraud is a federal crime with serious consequences, and USCIS scrutinizes this question carefully at every stage.

Evidence of a bona fide marriage frequently submitted includes joint financial accounts and shared financial responsibilities, lease or mortgage agreements showing cohabitation, photographs spanning the course of the relationship, communication records, joint travel documentation, affidavits from people with personal knowledge of the relationship, and birth certificates of any children born to the marriage. In most cases, both spouses must attend an in-person interview where a USCIS officer or consular officer will ask questions about the relationship directly.

Two paths: adjustment of status vs. consular processing

How a couple applies depends on where the foreign spouse is located.

Adjustment of status is available to foreign spouses already inside the United States on a valid visa or through another lawful entry. The process begins with the U.S. citizen or Green Card holder filing Form I-130, Petition for Alien Relative, with USCIS. If the sponsor is a U.S. citizen, Form I-485 — the adjustment of status application — may be filed concurrently. If the sponsor is a Green Card holder, Form I-485 cannot be filed until the priority date is current. Additional steps include a biometrics appointment, a medical examination completed by a USCIS-designated civil surgeon using Form I-693, and an in-person interview. If approved, the Green Card is mailed to the address on file.

Consular processing is used when the foreign spouse lives abroad or is otherwise ineligible to adjust status from within the United States. After USCIS approves Form I-130, the case is transferred to the National Visa Center (NVC), which collects fees and gathers documentation. The foreign spouse completes Form DS-260, the online immigrant visa application. Supporting documents including civil records, financial documentation, and Form I-864, Affidavit of Support, are submitted through the NVC portal. The applicant then completes a medical examination with an embassy-approved physician and attends an interview at the U.S. embassy or consulate in their home country. If approved, an immigrant visa is placed in the passport, and the applicant must enter the United States within six months.

Conditional Green Cards

If the couple has been married for less than two years at the time the Green Card is approved, USCIS issues a conditional Green Card valid for two years. This condition exists as a safeguard against immigration fraud. To convert the conditional card to a standard 10-year card, the couple must jointly file Form I-751, Petition to Remove Conditions on Residence, during the 90-day window before the card expires. USCIS may schedule an additional interview before approving the petition.

If the marriage ends before Form I-751 is filed — due to divorce, the death of a spouse, or abuse — a waiver of the joint filing requirement may be available depending on the circumstances.

Processing times and costs

Processing times vary considerably depending on the sponsor’s immigration status, the processing route, and current USCIS and consular workloads. Spouses of U.S. citizens applying through adjustment of status frequently wait approximately 10 to 24 months from filing to approval. Consular processing typically adds time beyond the Form I-130 processing period, with embassy interview scheduling varying by location.

Government filing fees for a marriage-based Green Card vary by route. For adjustment of status applicants, fees include $625 for Form I-130 online ($675 by mail), $1,390 for Form I-485 online ($1,440 by mail), and optional fees for Form I-765 and Form I-131. For consular processing applicants, fees include the Form I-130 filing fee, a $325 immigrant visa application fee, a $120 Affidavit of Support fee, a medical examination cost, and a $235 USCIS immigrant fee paid after visa approval. All fees should be verified on the USCIS filing fees page and the Department of State visa fees page before submitting, as they are subject to change.

The path to citizenship

Spouses of U.S. citizens who hold a marriage-based Green Card may apply for naturalization after three years of permanent residence — rather than the standard five years — provided they have remained married to and living with the same U.S. citizen spouse throughout that period and meet all other naturalization requirements. The three-year clock includes any time spent as a conditional resident.

The value of legal guidance

The marriage-based Green Card process involves detailed documentation requirements, a demanding evidentiary standard for proving a genuine marriage, and procedural timelines that vary by processing route and individual circumstances. For couples navigating this process — particularly those with prior immigration complications, prior marriages, or other factors that may require additional documentation — working with experienced immigration counsel is a practice frequently associated with stronger applications and fewer avoidable delays.
