Marrying a US citizen is the fastest, most reliable path to a green card in the US immigration system. If you qualify, you qualify — no lottery, no cap, no priority date to wait for. That’s the good news.
The bad news is that “fastest and most reliable” still means twelve to eighteen months of paperwork, government scrutiny of your relationship in detail, and a process that fundamentally forks into two very different versions depending on where the foreign spouse is standing on the day you file.
This page is the long version: what the marriage-based green card actually is, who qualifies, the two possible paths (consular processing vs. adjustment of status), what everything costs, how long it really takes, what officers look for when they decide whether your marriage is real, and what kills petitions.
If you’re figuring out whether to pursue this at all, start at the top. If you’re already in the middle of a filing, skip to the section that matches your path.
A note: If you’re worried about encountering US Immigration and Customs Enforcement (ICE) at any point in this process, our Know Your Rights guide covers what to do.
What the marriage-based green card actually is
The marriage-based green card is lawful permanent residence (LPR status — a green card) granted on the basis of marriage to a US citizen or lawful permanent resident. The term covers two slightly different visa categories:
- IR-1 (Immediate Relative, spouse of a US citizen) — issued if the couple has been married for more than two years at the time the green card is approved. This is a full, unconditional green card.
- CR-1 (Conditional Resident, spouse of a US citizen) — issued if the couple has been married for less than two years at the time of approval. This is a conditional two-year green card that converts to permanent status after the couple files Form I-751 (Petition to Remove Conditions) to prove the marriage is still real.
Both categories live in the “immediate relative” tier of US family-based immigration, which means no numerical cap and no visa backlog. This is the key distinction between marrying a US citizen and almost every other family-based path. Spouses of lawful permanent residents (green card holders rather than citizens) fall into the F-2A category, which has a cap and can involve waiting years for a visa to become available. Spouses of US citizens do not.
So if the sponsoring spouse is a US citizen, the question isn’t “will there eventually be a green card available?” It’s “how long will the paperwork take?”
Who qualifies
Three things have to be true:
1. There’s a real, legally valid marriage. The marriage has to be legally recognized where it was performed and recognized under US federal law. Same-sex marriages qualify, marriages performed abroad qualify if valid in the country where they occurred, and common-law marriages qualify in some circumstances. What doesn’t qualify: marriages entered into primarily to get a green card. More on this below — it’s the single most scrutinized aspect of the entire process.
2. The sponsoring spouse is a US citizen or lawful permanent resident. US citizens can sponsor through the “immediate relative” category (no cap, no wait). Green card holders can sponsor through F-2A (cap applies, modest wait).
3. The foreign spouse is admissible to the US. Prior immigration violations, certain criminal history, health-related grounds, and misrepresentation issues can all create inadmissibility problems. Some are waivable; some are not. If any of these exist, don’t file without first understanding whether a waiver is possible and what it requires.
The two paths: consular processing vs. adjustment of status
This is the fork that shapes everything else about your experience. Where the foreign spouse is physically standing when you file determines which path applies.
Consular processing (CR-1 / IR-1)
Used when the foreign spouse is outside the US. The sponsoring spouse files Form I-130 (Petition for Alien Relative) with US Citizenship and Immigration Services (USCIS). Once approved, the case transfers to the National Visa Center (NVC) for pre-processing, then to the US embassy or consulate in the foreign spouse’s home country for the final interview and visa issuance. The foreign spouse enters the US as a lawful permanent resident on the day they arrive with their visa.
Timeline: roughly 12–18 months start to finish, depending on the service center and consulate.
Adjustment of status (AOS)
Used when the foreign spouse is already in the US on some other valid status (work visa, student visa, visitor visa with no immigrant intent at entry, etc.). The sponsoring spouse files Form I-130 and the foreign spouse files Form I-485 (Application to Register Permanent Residence or Adjust Status), typically at the same time (“concurrent filing”). The entire process happens inside the US. The foreign spouse can usually get work authorization (EAD — Employment Authorization Document) and travel permission (Advance Parole) while the case is pending, and attends the final interview at a local USCIS field office.
Timeline: roughly 8–14 months start to finish, though the EAD and travel documents typically arrive in 3–5 months.
Which path applies to you
- Foreign spouse outside the US → consular processing. No choice.
- Foreign spouse inside the US on a valid non-immigrant status → adjustment of status. The usual path.
- Foreign spouse inside the US without status, or who entered without inspection → complicated. May or may not be eligible for AOS depending on how they entered and whether they qualify for specific protections (INA 245(i) in rare cases, or VAWA self-petitioning in different circumstances). This is the scenario where you need an attorney before you file anything.
Insider note: The temptation to have a foreign fiancé(e) visit on a tourist visa, get married here, and then file AOS is one of the most dangerous moves in the entire family-based immigration system. If the foreign spouse entered the US on a visitor visa with the intention of staying, that’s fraud at the port of entry, and USCIS can and does deny AOS applications on that basis. The safe paths are either consular processing (foreign spouse applies from abroad), or the K-1 fiancé(e) visa (foreign spouse enters specifically to marry within 90 days), or AOS only when the marriage was genuinely unplanned when the foreign spouse entered. The “90-day rule” is real — USCIS presumes misrepresentation if someone marries within 90 days of entering on a non-immigrant visa.
The consular path, step by step
For couples where the foreign spouse is abroad:
1. File Form I-130. The US citizen or LPR spouse files this with USCIS. Filing fee is $675 when filed online, $625 when filed by mail. The petition establishes that a valid marriage exists.
2. Wait for I-130 approval. Currently 10–15 months at most USCIS service centers. This is the slowest part of the process.
3. Case transfers to the National Visa Center. Once I-130 is approved, the case moves to NVC for pre-processing. The couple pays visa processing fees (currently $325 for the immigrant visa application and $120 for the affidavit of support review), submits civil documents (birth certificates, police certificates, marriage certificate), and the sponsoring spouse submits Form I-864 (Affidavit of Support) demonstrating they can financially support the foreign spouse.
4. Interview scheduled at the US embassy or consulate. Wait times vary dramatically by country. Some consulates schedule within weeks of NVC processing completion; others are backlogged by many months.
5. Medical exam. The foreign spouse completes a required medical exam with a panel physician approved by the consulate.
6. Consular interview. The foreign spouse attends, and the consular officer makes the decision. Interview preparation is covered in the Marriage-Based Green Card Playbook (coming soon).
7. Visa issuance and travel to the US. Once approved, the foreign spouse receives the immigrant visa in their passport. They have six months to enter the US. On entry, they are admitted as a lawful permanent resident, and the physical green card arrives in the mail at the US address a few weeks later.
The adjustment of status path, step by step
For couples where the foreign spouse is already in the US on valid status:
1. File concurrently: I-130, I-485, I-765, I-131. This is the standard concurrent filing package:
- Form I-130 (Petition for Alien Relative) — establishes the marriage
- Form I-485 (Application to Register Permanent Residence) — applies for the green card itself
- Form I-765 (Application for Employment Authorization) — requests the EAD work card
- Form I-131 (Application for Travel Document) — requests Advance Parole for international travel
Filing fees total $3,005 for most adults ($1,440 for the I-485 alone, plus the I-130 and biometrics). The I-765 and I-131 are free when filed concurrently with the I-485.
2. Biometrics appointment. The foreign spouse attends a fingerprinting appointment at an Application Support Center. Usually 2–6 weeks after filing.
3. EAD and Advance Parole arrive. Typically 3–5 months after filing. The EAD lets the foreign spouse work; the AP lets them travel internationally and return without abandoning the pending AOS.
4. Interview scheduled at a local USCIS field office. Usually 6–12 months after filing, though some field offices run faster or slower. Both spouses must attend together.
5. The interview itself. A USCIS officer reviews the documents and asks questions about the marriage and relationship. The interview is where most marriage-based AOS cases are decided. Preparation matters — the Marriage-Based Green Card Playbook (coming soon) covers it in depth.
6. Green card issued. If approved and the marriage is less than two years old, the foreign spouse gets a conditional two-year green card (CR status). If the marriage is more than two years old at approval, they get a full ten-year green card (IR status).
What it costs
Consular processing (CR-1 / IR-1):
- I-130 filing fee: $675 online / $625 by mail
- NVC immigrant visa application fee: $325
- NVC affidavit of support fee: $120
- Medical exam: typically $200–500, varies by country
- Document translations, civil documents, passport photos: $100–300
- Attorney fees (if used): typically $2,000–5,000 for a straightforward case
Total out-of-pocket: roughly $1,400–2,000 without an attorney, $3,500–7,000 with one.
Adjustment of status (I-485):
- I-130 filing fee: $675 online / $625 by mail
- I-485 filing fee: $1,440 (adult)
- Biometrics fee: $0 (bundled into I-485 for most applicants)
- I-765 and I-131 (EAD and Advance Parole): $0 when filed concurrently with I-485
- Medical exam: typically $200–500
- Attorney fees (if used): typically $2,500–6,000
Total out-of-pocket: roughly $2,200–3,000 without an attorney, $5,000–9,000 with one.
Insider note: Attorney fees for marriage-based cases vary wildly. The spread isn’t a reflection of quality so much as of how much hand-holding the attorney is providing and how complicated the case is. A straightforward marriage with no prior immigration issues, no criminal history, and clean documentation can be handled competently for $2,500. A case with any complications — prior overstays, prior denials, immigration fraud history, criminal issues, or waivers required — can legitimately cost $8,000+ and is often worth it. The warning sign isn’t price; it’s any attorney who guarantees an outcome or doesn’t ask detailed questions before quoting a fee.
How long it really takes
Rough ranges based on current USCIS processing times. These shift frequently.
Consular processing:
- I-130 adjudication: 10–15 months
- NVC processing: 2–4 months
- Consular interview scheduling: 1–6 months (varies dramatically by country)
- Total: typically 13–20 months
Adjustment of status:
- I-485 processing including interview: 8–14 months
- EAD and Advance Parole: 3–5 months after filing
- Total green card: typically 8–14 months
Removing conditions (for CR-1 cases): Separate process required within the 90 days before the two-year conditional green card expires. Form I-751 filing fee is $750, and processing currently runs 12–30 months. During this time, the conditional green card is auto-extended by a receipt notice.
What officers actually look at
Marriage-based cases are decided on one question: is this marriage real, or was it entered into primarily to get a green card?
The evidence that proves “real” takes two broad forms:
Documentary evidence of shared life. Joint financial accounts, lease or mortgage in both names, joint tax returns, joint insurance, shared household bills, photos together across time and contexts, travel together, children together if applicable, and affidavits from people who know you as a couple.
Testimonial evidence at the interview. Both spouses able to answer basic questions about each other and their shared life, consistently with each other when asked separately. The officer is testing whether the couple’s answers reflect a real shared life or a rehearsed story.
Insider note: I’ve prepared thousands of couples for these interviews in Chicago. The couples who struggle aren’t the ones with unusual circumstances or complicated backgrounds — they’re the ones who treat the interview as a formality or who over-rehearse. Officers process many marriage-based cases a year and have seen every form of fraud. Your real marriage has to be documented and presented in a way that distinguishes it from the fraudulent ones they’ve trained to spot. That’s not a comment on your relationship; it’s a comment on what the system requires. The Marriage-Based Green Card Playbook (coming soon) covers interview preparation in depth — what officers actually ask, how to prepare without over-rehearsing, how to handle unexpected questions, and the common patterns that trip up legitimate couples.
What kills marriage-based petitions
In rough order of frequency:
1. Insufficient evidence that the marriage is real. The classic failure mode: filing with just the marriage certificate and a few photos, assuming the officer will take the marriage at face value. For couples whose marriages are legitimate, this is fixable with better evidence — but the time to compile it is before filing, not in response to a Request for Evidence (RFE) when memory of specific dates and interactions has faded.
2. Inconsistent interview testimony. When officers interview spouses separately and compare answers, inconsistencies raise flags. Most inconsistencies are innocent — people genuinely remember things differently. But patterns of serious inconsistency (where you met, when you started dating, who proposed) can sink an otherwise valid case.
3. Prior immigration violations. Overstays, prior deportation orders, prior fraud, prior misrepresentation to immigration officials — any of these can create inadmissibility problems that waivers may or may not solve. The time to address these is before filing, not after.
4. The 90-day rule situation. As described above, marriages that happen within 90 days of the foreign spouse entering on a non-immigrant visa are presumed by USCIS to involve misrepresentation of intent at entry. This can be rebutted, but it’s an uphill fight.
5. Insufficient Affidavit of Support. The sponsoring spouse has to demonstrate income at or above 125% of the federal poverty guidelines for the household size. If the sponsoring spouse doesn’t earn enough, a joint sponsor can be used, but this adds complexity and requires its own evidence. Underestimating this requirement sinks cases regularly.
6. Criminal history problems. Certain crimes make a sponsoring US citizen ineligible to sponsor (Adam Walsh Act for crimes against children, for example), and certain crimes make a foreign spouse inadmissible. Not every criminal history is disqualifying, but it needs to be assessed before filing.
Removing conditions (for CR-1 cases)
If the couple was married less than two years when the green card is approved, the foreign spouse receives a conditional two-year green card. In the 90 days before it expires, the couple files Form I-751 (Petition to Remove Conditions on Residence) to convert it to a full ten-year green card.
The I-751 filing is essentially a second round of proving the marriage is real — but now with another two years of evidence of shared life. Joint accounts should have grown, joint tax returns should exist for the married years, photos should span the full period, and (if applicable) children may have been born.
Filing fee: $750. Processing time currently runs 12–30 months, during which the conditional green card is auto-extended by the receipt notice.
Divorces that happen during the conditional period complicate but don’t necessarily end the case. The foreign spouse can file an I-751 with a waiver of the joint filing requirement if the marriage was legitimate when entered into but ended through divorce, death, or in cases of abuse. These waivers are available but require strong evidence and often legal help.
After approval
Once the green card is issued (whether unconditional at the start, or after removing conditions):
- The foreign spouse is a lawful permanent resident. They can live and work anywhere in the US indefinitely.
- Travel is allowed, with limits. Trips abroad shorter than six months are usually fine. Longer trips can raise abandonment-of-residence questions. Trips longer than one year require a re-entry permit filed before leaving.
- Naturalization is possible after three years. Spouses of US citizens are eligible to naturalize (become US citizens themselves) after three years of permanent residence, provided they’re still married to and living with the same US citizen spouse. For spouses of lawful permanent resident sponsors, the wait is five years.
- Sponsorship obligations continue. The sponsoring spouse’s I-864 Affidavit of Support remains legally enforceable until the foreign spouse becomes a US citizen, dies, or has 40 qualifying quarters of US work history. This can matter in divorce proceedings.
If you don’t qualify or your case is complicated
Not every situation fits cleanly into the standard path. Some scenarios where you need an attorney before filing anything:
- The foreign spouse is in the US without status, entered without inspection, or has prior removal orders
- Either spouse has prior immigration fraud or misrepresentation history
- Either spouse has significant criminal history
- The marriage happened within 90 days of the foreign spouse entering on a non-immigrant visa
- The sponsoring spouse doesn’t meet income requirements and no obvious joint sponsor is available
- Prior denied immigration petitions exist for either spouse
- The couple has been separated for substantial periods during the marriage
- There’s a prior I-751 denial or a prior marriage-based petition denial
Where to go from here
If this is your first time looking at the marriage-based green card:
- Trying to figure out which path applies to you? The quick test is where the foreign spouse is physically standing today. Abroad = consular processing. Inside the US on valid status = adjustment of status. If neither cleanly applies, you need an attorney before filing.
- Already filed and waiting? The two most common waiting-period mistakes are international travel without Advance Parole (which can be treated as abandonment of the AOS application) and missing RFE deadlines. Both are preventable.
- Not sure if your evidence is strong enough? The time to find out is before you file, not after USCIS tells you.
The marriage-based green card is the most reliable path in US immigration if you qualify and your situation is clean. The failure modes are almost all preventable with good preparation — specific, well-documented evidence of a real shared life, accurate affidavits of support, and clean handling of any complications before filing rather than after.
The Beyond the Form Marriage-Based Green Card Playbook (coming soon) walks through every strategic decision point in detail — the specific evidence that officers find most persuasive, how to prepare for the interview, how to handle common complications, and what to do if you get an RFE.
