Quick Summary: A UK-based spouse seeking a US marriage green card normally proceeds through Form I-130, National Visa Center (NVC) processing, a panel-physician medical examination, and an immigrant-visa interview at the US Embassy in London. After visa issuance and US admission, the spouse is admitted as a lawful permanent resident. Careful preparation of relationship, financial, civil, and medical evidence is essential throughout the CR-1/IR-1 consular process.
Expert legal guidance at Crownside Legal helps UK applicants successfully navigate the complex document preparation and interview stages at the US Embassy in London.

How a UK-Based Spouse Applies for a US Marriage Green Card
For British citizens, UK permanent residents, and expatriates married to a United States citizen or lawful permanent resident (LPR), a US marriage green card is typically pursued through the consular immigrant-visa process. The UK-based route culminates in an in-person immigrant-visa interview at the Embassy of the United States in London at Nine Elms. On approval and admission to the United States, the foreign spouse is admitted as a lawful permanent resident.
This guide follows the main stages involving USCIS, the National Visa Center (NVC), and the US Embassy in London. Individual eligibility, timing, documentary requirements, and fees can change, so applicants should verify current official requirements before filing.
The London Consular Processing Journey at a Glance
Stage 1 — USCIS petition: Form I-130 and Form I-130A establish petitioner status and the bona fide marriage.
Stage 2 — NVC pre-processing and documentary qualification: DS-260, Form I-864, fees, and supporting documents are submitted.
Stage 3 — UK visa medical: a designated panel physician completes the medical examination, police-certificate review, and vaccination assessment.
Stage 4 — Immigrant-visa interview: the London consular officer reviews original documents and adjudicates the case.
Stage 5 — US entry and resident-card production: the endorsed passport operates as temporary evidence of permanent-resident status after admission.

Step 1: File Form I-130 with USCIS
The process begins when the US citizen or LPR spouse, as petitioner, files for the UK-based beneficiary through USCIS.
Primary forms: Form I-130 (Petition for Alien Relative) and Form I-130A (Supplemental Information for Spouse Beneficiary).
Filing fee: The source material lists $625 for online filing and $675 for paper filing. Fees can change and should be verified before submission.
Core evidentiary burden: The petitioner must establish US citizenship or LPR status and a legally valid, bona fide marriage. Relevant evidence can include shared financial commitments, joint leases or deeds, travel history, photographs across time, and sworn affidavits.
Timing: The source material estimates 10–14 months for USCIS adjudication. Actual timelines vary.

Step 2: National Visa Center Processing and Documentary Qualification
After USCIS approves Form I-130, the petition is transferred to the Department of State's National Visa Center in Portsmouth, New Hampshire. The NVC assigns a London case number and invoice identification number, then coordinates fee payments and documentary uploads through the Consular Electronic Application Center (CEAC).
NVC fees: The source material lists a $325 DS-260 immigrant-visa application processing fee per applicant and a $120 Form I-864 affidavit-of-support review fee per case.
Form DS-260: The UK spouse submits the online immigrant-visa electronic application.
Form I-864 Affidavit of Support: The US petitioner must show household income meeting 125% of the applicable Federal Poverty Guidelines, supported by recent IRS tax transcripts and W-2s or 1099s. The source material identifies approximately $26,437 for a two-person household; the current Form I-864P must be checked. A US-domiciled qualifying joint sponsor may be used if the petitioner cannot meet the threshold alone.
Civil documents: The source material identifies the UK passport biographic page, certified long-form birth certificate listing parents, certified marriage certificate, final divorce decrees or annulments where applicable, ACRO police certificate, and military or court records where applicable.
Documentarily qualified stage: Once fees and documents are accepted, the NVC issues a Documentary Qualified notification and queues the case for an interview appointment at the London Embassy.

Step 3: Visa Medical Examination in London
All UK immigrant-visa applicants must complete a medical examination with the Embassy's designated panel physician before the interview. The source material identifies Visa Medicals Ltd in London as the relevant panel clinic, with appointments generally booked 10–14 days before the interview so results are available in time. Applicants should verify current clinic instructions directly before booking.
Medical components: The examination includes a physical assessment and medical-history review, potentially a chest X-ray and age-dependent laboratory testing, plus the CDC-required vaccination assessment. The source material identifies MMR, Tdap/DTP, varicella, hepatitis B, and seasonal influenza among the relevant vaccines.
Estimated cost: The source material estimates £400–£450 for a standard adult medical examination, excluding any additional vaccines or specialist testing.

Step 4: Immigrant Visa Interview at the US Embassy in London
When an interview appointment becomes available, the NVC emails the applicant the appointment letter. The source material identifies the US Embassy location as 33 Ponton Road, Nine Elms, London, SW11 7US. Applicants should follow the appointment notice and current Embassy instructions, including any courier-registration requirements.
What to bring: The source material identifies the interview letter, DS-260 confirmation page, valid passport, two US-specification passport photographs, original or certified civil documents, and updated financial-sponsorship evidence such as current tax transcript, employment letter, and recent payslips.
Interview adjudication: The consular officer administers an oath, verifies documents, confirms receipt of the medical results, and asks questions about the relationship history, marriage, and intended life in the United States.

Step 5: Visa Issuance, USCIS Immigrant Fee, and US Entry
If approved, the consular officer retains the passport to place the immigrant visa foil in it. The visa classification depends on how long the couple has been married on the date of US admission.
CR-1 conditional resident: A spouse admitted before the second marriage anniversary receives conditional resident status. The resulting card is valid for two years, and Form I-751 is generally required before expiry to seek removal of conditions.
IR-1 immediate relative: A spouse admitted after two or more years of marriage receives an unconditional permanent-resident card under the IR-1 classification.
USCIS immigrant fee and entry: The source material lists a $235 immigrant fee before travel so the physical card can be produced and sent to the US address. The endorsed immigrant visa serves as temporary Form I-551 evidence of permanent-resident status for up to one year, authorising work and travel subject to applicable requirements.

Frequently Asked Questions (FAQ)
Can the US citizen spouse attend the interview in London?
Yes, but it is not mandatory. The US citizen petitioner may accompany the foreign spouse to the Embassy in Nine Elms, but their physical presence is not generally required for consular interview approval.
Can I travel to the US on ESTA while my green card application is pending?
Possibly, but it is subject to strict border scrutiny. A pending Form I-130 or consular case does not itself prevent a short temporary visit through ESTA or a B-1/B-2 visa, but the traveller must be able to satisfy Customs and Border Protection that the visit is temporary and that they will depart to complete consular processing in London. Evidence of UK ties can be important.
Can we expedite the process through Direct Consular Filing in London?
Only in exceptional qualifying circumstances. The source material explains that routine Form I-130 filings go to domestic USCIS lockboxes, while Direct Consular Filing may be available for a US citizen resident in the UK who faces an emergent humanitarian situation, sudden military redeployment, or short-notice corporate relocation to the United States.
What if I have a past police caution or arrest in the UK?
All arrests, cautions, and convictions should be disclosed. The source material states that US immigration law does not treat UK spent convictions in the same way as the UK Rehabilitation of Offenders Act. An ACRO certificate and, where required, court records or a memorandum of conviction may be needed. Depending on the offence and its immigration consequences, a Form I-601 waiver of inadmissibility may need to be evaluated.
