Americans Moving to the UK

Moving to the UK as an American — the big picture

Let's start with the single most important distinction, because getting it wrong causes real problems at the border. There is a difference between visiting the UK and moving to the UK, and they involve completely different permissions.

If you only want to visit — a holiday, seeing family, a short business trip — you generally do not need a visa as a US citizen. Instead, you'll need an Electronic Travel Authorisation (ETA), which we explain below. But an ETA is strictly for short stays. It does not let you live, work or settle in Britain.

If you want to move — to live with a partner, take a job, build a business, study a long course, or eventually settle permanently — you need a visa under one of the UK's immigration routes. Each route has its own eligibility rules, costs and conditions, and most lead, in time, to settlement (called 'indefinite leave to remain', or ILR) and then potentially British citizenship.

The right route depends on your circumstances: your relationships, your work, your background and your plans. There is rarely only one option, and choosing well at the start can save you years and a great deal of money. That's exactly the kind of thing our network of solicitors helps Americans untangle.

Visiting versus moving: the ETA explained

The Electronic Travel Authorisation (ETA) is a relatively new requirement, and a lot of Americans are unsure what it is. In short: it is not a visa. It is a digital pre-travel permission, linked to your passport, that most visitors — including US citizens — now need before they travel to the UK for a short stay.

An ETA covers tourism, visiting friends and family, and certain business activities, and it allows visits of up to six months. You apply online and pay a fee set by GOV.UK; it is much simpler and cheaper than a visa. Once granted, it typically lets you make multiple short trips over a period of time, rather than just one.

The crucial limitation: an ETA does not allow you to live, work for a UK employer, study a long course, or settle. If your plan is to make the UK your home, the ETA is not your route — you need a proper visa. Treating an ETA as a back-door to living in the UK can lead to refused entry and future immigration problems.

• ETA = short visits only (up to six months), not living or working
• Most US citizens need an ETA to visit the UK
• It is not a visa and does not lead to settlement
• Always check current ETA requirements and fees on GOV.UK before you travel

Route 1: Spouse or Partner visa (a strong route for many Americans)

If you're married to, in a civil partnership with, or in a long-term relationship with a British citizen or someone settled in the UK, the partner (often called 'spouse') route is one of the most common ways Americans move over. It lets you live in the UK with your partner and, in time, settle.

You'll need to show your relationship is genuine and ongoing — through marriage or civil partnership, or by proving you've been living together in a relationship for a sustained period. You'll also need to meet a financial requirement, which exists to show the couple can support themselves without relying on public funds. The exact income thresholds and the ways you can meet them are set by GOV.UK and change from time to time, so we never quote them as fixed figures.

Here's a genuine advantage for Americans: the UK normally requires partner-visa applicants to prove their knowledge of English, but nationals of certain majority English-speaking countries are exempt — and the USA is on that list. So as a US citizen you generally won't have to sit an English language test for this route. (Always confirm your exemption applies to your specific circumstances.)

The partner visa is usually granted for an initial period of just under two and a half years, after which you extend it, before becoming eligible to apply for settlement once you've completed the required continuous time in the UK on this route. The financial and documentary side is detailed, and small mistakes cause refusals — which is where careful preparation pays off.

• For partners of British citizens or settled persons
• Must prove a genuine relationship and meet the financial requirement
• US citizens are generally exempt from the English language test
• Leads to settlement (ILR) after the required time on the route
• Thresholds and rules: always check the current position on GOV.UK

Route 2: Skilled Worker visa (move for a job)

If a UK employer wants to hire you, the Skilled Worker visa is the main work route. It's employer-led, so the first thing you need is a confirmed job offer from a UK employer that holds a Home Office sponsor licence (an 'approved sponsor').

That sponsor issues you a Certificate of Sponsorship (CoS) — essentially an electronic record confirming the job, the role and the details of your employment. Your job must be on the list of eligible occupations, and you must be paid at or above the salary threshold that applies to your role. These thresholds vary by occupation and are set by GOV.UK, so we'd check the current figures for your specific job rather than rely on memory.

A Skilled Worker visa can be granted for up to five years before extension, and crucially it can lead to settlement: after the required continuous period working in the UK on this route, you can usually apply for indefinite leave to remain. Your partner and children can generally come with you as dependants. There are also specific arrangements for health and care workers in some cases.

For many Americans, the practical hurdle isn't the visa itself but securing a sponsoring employer. If you have an offer in hand, this route is often straightforward; our solicitors can help you and your employer get the CoS and application right.

• Needs a job offer from a Home Office-approved UK sponsor
• Requires a Certificate of Sponsorship (CoS)
• Role must be eligible and meet the relevant salary threshold (per GOV.UK)
• Up to five years, extendable, and can lead to settlement
• Partner and children can usually join as dependants

Route 3: Citizenship by descent and the UK Ancestry visa

Before looking at visas, it's worth checking whether you might already be British — or entitled to be. Some Americans are British citizens 'by descent' through a parent, often without realising it. If you have a British parent, it's well worth investigating, because if you're already a citizen you may not need a visa at all.

The UK Ancestry visa is a separate, popular route — but here's the catch that trips up a lot of Americans. The Ancestry visa is only open to Commonwealth citizens (plus a few other specific categories) who have a grandparent born in the UK, the Channel Islands or the Isle of Man. The United States is not a Commonwealth country, so being a US-only citizen does not qualify you for the Ancestry visa, even if you do have a UK-born grandparent.

Where this can become relevant is if you hold dual nationality with a Commonwealth country (for example, Canada, Australia or another Commonwealth state) as well as your US citizenship. In that case the Ancestry route might be open to you. This is an area where a quick check of your family tree and your passports can reveal options you didn't know you had.

• You might already be British 'by descent' through a parent — worth checking first
• The Ancestry visa needs a UK-born grandparent AND Commonwealth citizenship
• US-only citizens generally cannot use the Ancestry visa
• Dual nationals with a Commonwealth country may qualify — get it checked

Route 4: Global Talent, business and innovator routes

If you're a leader, or a rising leader, in your field, the Global Talent visa is worth a serious look. It's aimed at exceptional people in academia and research, arts and culture, and digital technology. Rather than a job offer, it generally relies on an endorsement from an approved body confirming your standing (or, in some cases, holding an eligible prestigious prize).

Global Talent is flexible and prized for good reason: you typically don't need a sponsoring employer, you can work for yourself or others, and it can lead to settlement — sometimes faster than other routes, depending on your field. For founders, researchers, designers, engineers and senior creatives, it can be a much better fit than a standard work visa.

There are also routes for people building or running businesses in the UK, such as the Innovator Founder route for those with an innovative, viable and scalable business idea backed by an approved endorsing body. These business routes have specific requirements and assessments, so they suit some entrepreneurs far better than others — and the right choice depends on the detail of your plans.

• Global Talent: for leaders/potential leaders in academia, research, arts, tech
• Usually needs an endorsement rather than a job offer
• Flexible, and can lead to settlement
• Innovator Founder route exists for entrepreneurs with an endorsed business idea

Route 5: Student routes (a brief word)

If your main reason for coming is to study, the Student visa lets you take a longer course at a licensed UK education provider, which must sponsor you. It's a popular way for younger Americans to spend time in the UK, and some students later move onto work or family routes.

After certain courses, the Graduate visa can allow you to stay and work or look for work for a period after graduating, without needing a sponsor straight away. Student routes have their own rules on finances, sponsorship and what work you can do alongside study, so check the current GOV.UK guidance for your course and provider.

Choosing the right route — a quick decision guide

With several options on the table, it helps to match your main reason for moving to the most likely route. The following is a simplified starting point, not a substitute for advice — many people qualify under more than one route, and the best choice isn't always the obvious one.

If two routes are open to you, factors like cost, how quickly each leads to settlement, work flexibility and your family's needs can tip the balance. That comparison is exactly what a free assessment is for.

• Moving to be with a British/settled partner → Spouse/Partner visa
• You have a UK job offer from a licensed sponsor → Skilled Worker visa
• You're a leader in academia, tech, arts or research → Global Talent
• You have a British parent → check if you're already British by descent
• You're a dual national with a Commonwealth country + UK-born grandparent → possibly Ancestry
• You want to study a longer course → Student visa
• You only want a short visit → ETA, not a visa

The Immigration Health Surcharge and NHS access

One cost that surprises many Americans is the Immigration Health Surcharge (IHS). Most people applying for a visa to live in the UK for more than six months must pay the IHS as part of their online application, usually upfront and per person — so it applies to your dependants too.

In return, paying the IHS gives you access to the National Health Service (NHS) on broadly the same basis as a UK resident from the day your visa starts. That means you can register with a doctor and use the NHS without being charged for most care, though some things (like prescriptions and dental treatment) still carry standard charges.

The IHS amount is set by GOV.UK and is calculated according to the length of your visa, so we won't quote a figure here — but do budget for it carefully, as for a family over several years it can be a significant sum on top of the visa fee itself.

• Most long-stay visa applicants must pay the IHS, including for each dependant
• It gives NHS access from the start of your visa
• Some NHS services still carry standard charges
• Amount is set by GOV.UK and depends on visa length — budget for it early

Biometrics, documents and how applications work

Most UK visa applications are made online, and the process is more streamlined than it used to be — but it's also detail-heavy, and the documents you provide make or break the outcome.

You'll usually complete an online form, pay the application fee and the IHS, and then confirm your identity. Many applicants now do this using a smartphone app to scan their passport, while others attend a visa application centre to give biometrics (fingerprints and a photo). After a successful application, your immigration status is increasingly held digitally as an 'eVisa' rather than a sticker in your passport.

The supporting documents differ by route — for a partner visa you're proving a relationship and finances; for a Skilled Worker visa your sponsor and CoS do much of the heavy lifting. Translations, the right financial evidence in the right format, and consistent details across documents all matter. A surprising number of refusals come down to avoidable paperwork errors rather than genuine ineligibility, which is precisely where careful preparation helps.

• Most applications are online, with identity confirmed by app or at a visa centre
• Biometrics (fingerprints and photo) are often required
• Status is increasingly digital — an 'eVisa' rather than a passport sticker
• Document accuracy and the right financial evidence are critical

Bringing your family (dependants)

Moving as a family? Most of the main routes let you bring your partner and children with you as 'dependants', so you don't have to be separated. On a Skilled Worker or Global Talent visa, for example, your spouse or partner and children under 18 can usually apply to join you.

Each dependant has their own application, their own fee and, in most cases, their own Immigration Health Surcharge — so the total cost for a family is considerably more than for one person. Dependants' permission is generally tied to yours, and in many cases your partner will be able to work in the UK.

Family situations can be more complex than they first appear — for example, children from a previous relationship, or a partner who'd actually qualify in their own right. It's worth mapping the whole family's position at the outset so everyone's status is secure and nobody is left out.

• Partners and children can usually come as dependants
• Each dependant needs their own application, fee and (usually) IHS
• Dependant partners can often work in the UK
• Plan the whole family's position together from the start

US and UK tax — an honest signpost

Here's something every American moving abroad needs to hear clearly: we are immigration solicitors, not tax advisers, and the points below are general signposting only, not tax advice.

The US is unusual in taxing its citizens on their worldwide income no matter where they live. That means even after you move to the UK, you'll generally still have US tax filing obligations, alongside whatever UK tax position applies once you're resident here. There are mechanisms — such as tax treaties and foreign tax credits — designed to reduce double taxation, but they're genuinely complex.

Please don't try to navigate this alone or assume it'll sort itself out. Before and after you move, speak to a qualified cross-border tax adviser who handles US/UK situations. Getting tax advice early, in parallel with your immigration application, is one of the smartest things an American moving to the UK can do.

• US citizens are generally taxed on worldwide income even while living abroad
• You may have both US and UK obligations once UK-resident
• Treaties and credits can reduce double taxation but are complex
• Speak to a qualified US/UK tax adviser — this is not tax advice

The path to settlement (ILR) and citizenship

For most people moving long-term, the goal is settlement: indefinite leave to remain, or ILR. ILR means you can live, work and study in the UK without an ongoing visa, free of most immigration conditions — and without paying the IHS each time you renew, because there's nothing to renew.

Most of the main routes lead to ILR after you've completed a required continuous period in the UK on that route — commonly around five years, though it can differ by route (some, like certain Global Talent cases, can be quicker). You'll usually also need to meet residence, knowledge-of-life-in-the-UK and other requirements at the settlement stage.

After holding ILR for the required period, many people go on to apply for British citizenship (naturalisation), which lets you hold a British passport. As an American, you'd want to consider the practicalities of dual nationality, including the tax points above. The exact requirements and timings for each stage are set by GOV.UK and should be confirmed for your route.

• ILR (settlement) frees you from most visa conditions and the IHS
• Usually reached after a required continuous period on your route
• Settlement involves residence and knowledge-of-life requirements
• Citizenship (naturalisation) can follow ILR — confirm current rules on GOV.UK
