Quick Summary: A US marriage green card and a UK spouse visa can both reunite married or civil partners, but their cost, timing, financial evidence, work rights, and route to citizenship differ significantly. The US CR-1/IR-1 route grants lawful permanent resident status on admission, while the UK Appendix FM partner route begins with time-limited leave and a longer settlement pathway. Your appropriate route depends on the couple's nationality, residence, financial position, evidence, and long-term plans.

US Marriage Green Card vs UK Spouse Visa: The Core Comparison
For international couples navigating cross-border relocation between the United States and the United Kingdom, the choice between a US marriage green card (lawful permanent residence) and a UK spouse visa under the Appendix FM partner route can be pivotal. While both pathways unite married partners and civil partners, they differ in fee structures, financial thresholds, administrative timelines, and routes to permanent settlement and dual citizenship.
Crownside Legal assists multinational couples across London, the UK, and internationally with strategic, compliant immigration applications spanning both jurisdictions.
Direct Comparison Overview
US Marriage Green Card (CR-1/IR-1 or adjustment of status): approval or entry confers lawful permanent resident status; the source material identifies consular government fees of approximately $1,355 and in-US adjustment of status costs of approximately $2,115–$3,005; consular timelines of 12–18 months and adjustment timelines of 8–14 months; a 125% Federal Poverty Guidelines financial threshold; and a three-year naturalisation path for qualifying spouses of US citizens.
UK Spouse Visa (Appendix FM): the initial grant is limited leave to remain for approximately 2.5 to 2.75 years; the source material identifies entry-clearance fees and IHS of £5,043 in total, standard out-of-country processing of 12–24 weeks, a £29,000 gross annual minimum income requirement or cash savings route, and a five-year route to indefinite leave to remain before a qualifying citizenship application.

1. Costs and Mandatory Government Fees
One of the sharpest contrasts between the two jurisdictions is the way mandatory government fees are structured and levied. Figures and filing fees can change, so couples should confirm current official charges before filing.
United States: Fee Structure
US fees are generally front-loaded and depend on whether the foreign spouse applies from outside the United States through consular processing or from within the country through adjustment of status (AOS).
Consular processing for a spouse living abroad: Form I-130 (Petition for Alien Relative) is listed in the source material at $675, or $625 if filed online; Department of State DS-260 and Affidavit of Support fees total $445; and the USCIS immigrant fee is $235 before entry. The stated base total is approximately $1,305–$1,355, excluding the required medical examination.
Adjustment of status inside the United States: the source material identifies combined Form I-130 and Form I-485 costs of approximately $2,065–$2,115, with optional ancillary filings including Form I-765 for employment authorisation and Form I-131 for advance parole travel authorisation.
United Kingdom: Fee Structure and Immigration Health Surcharge
The UK spouse visa can involve materially higher upfront statutory charges because of the Immigration Health Surcharge (IHS). The source material identifies an entry-clearance application fee of £1,938 plus an IHS of £3,105 for the initial 33-month grant, totaling £5,043. It also identifies further charges at the in-country FLR(M) extension stage and the ILR stage.

2. Processing Times and Expedited Services
Adjudication timelines vary with embassy workloads, administrative backlogs, local field office capacity, and expedited-process availability.
US Green Card Timelines
The source material estimates consular processing through the US Embassy London at 12–18 months, covering Form I-130 adjudication, National Visa Center document qualification, and the immigrant-visa interview. It estimates adjustment of status inside the United States at 8–14 months, depending on the local USCIS field office. It also notes that US immigration authorities do not offer paid priority service for marriage-based petitions; expedites are limited to qualifying extraordinary circumstances.
UK Spouse Visa Timelines
The source material identifies a standard out-of-country decision time of 12–24 weeks from biometrics, a priority-service decision time of approximately six weeks subject to a £500 surcharge, and a super-priority in-country decision by the next working day subject to a £1,000 surcharge. Availability and service standards can change.

3. Financial, Relationship, and Eligibility Requirements
US Requirements: Form I-864 Affidavit of Support
The US sponsoring spouse must demonstrate household income at 125% of the Federal Poverty Guidelines for the relevant household size. The source material identifies an approximate $26,437 figure for a two-person household. A qualifying joint sponsor who is a US citizen or lawful permanent resident domiciled in the United States may file a separate Form I-864 if the petitioner does not qualify alone.
UK Requirements: Appendix FM-SE
The source material identifies a £29,000 gross annual income requirement. It explains that third-party co-sponsorship is generally not available under the UK rules, but a shortfall may be addressed through qualifying cash savings held above £16,000 for at least six months; it identifies £88,500 as the liquid-cash amount to meet the requirement without employment income.
Relationship Evidence and Language Testing
Both USCIS and UK Visas and Immigration (UKVI) require robust contemporaneous evidence of a bona fide relationship, including relevant cohabitation records, joint financial evidence, travel history, shared leases or mortgages, and correspondence. The source material states that the US does not impose an English-language test for initial immigrant status, while the UK may require an approved Secure English Language Test unless an exemption applies, and also requires evidence of adequate accommodation.

4. Path to Settlement and Dual Citizenship
US green card route: a marriage green card provides lawful permanent resident status on entry or approval. If the marriage is under two years old at admission, the spouse receives conditional resident status and must address removal of conditions through Form I-751. A qualifying spouse of a US citizen may apply for naturalisation using Form N-400 after three years of continuous permanent residence while meeting the statutory requirements.
UK route: the applicant begins with time-limited leave to remain, applies for an extension after the initial period, completes a continuous five-year partner-route residence period, and must meet the relevant Life in the UK and English-language requirements before indefinite leave to remain. After ILR, a qualifying spouse of a British citizen may apply for British citizenship.

Frequently Asked Questions (FAQ)
Can my spouse work immediately upon arrival?
United States: A spouse entering with a CR-1 or IR-1 immigrant visa receives permanent-resident status on admission; the endorsed passport stamp functions as temporary evidence of that status. An applicant using adjustment of status inside the US needs Form I-765 employment authorisation before working unless another work-authorised status applies. United Kingdom: A UK spouse visa holder has permission to work from visa activation, subject to the visa's terms.
Can we use savings instead of employment income?
United States: Yes. Qualifying liquid assets such as savings, stocks, bonds, or other assets may be used if income is short; for a spousal case, the source material identifies a value equal to three times the income gap. United Kingdom: Yes. Qualifying cash savings above £16,000 held for at least six months may be used to meet or supplement the minimum income requirement.
Is a third-party co-sponsor permitted?
United States: Yes. A qualifying joint sponsor may file Form I-864 if the petitioner lacks sufficient income. United Kingdom: No. The source material states that third-party sponsorship is not permitted under the standard Appendix FM partner route.
What happens if our marriage is under two years old?
United States: The spouse is generally admitted as a two-year conditional resident (CR-1) and the couple generally must file Form I-751 within the statutory window to remove conditions. United Kingdom: The duration of the marriage does not alter the standard spouse-visa conditions or five-year settlement pathway.
