UK immigration rules are widely misunderstood, and acting on a myth can be expensive. Believing that marriage makes you British, that a visitor can work, or that overstaying is harmless can lead to a refused application, a wasted fee, or a re-entry ban. The Immigration rules are detailed, but the common misconceptions are straightforward to correct once you see what the law actually says. This post provides an overview of ten common UK immigration myths and the facts behind them.
Does marrying a British citizen make you British?
No. Marrying a British citizen does not give you British citizenship or an automatic right to live in the UK. Marriage is the start of a route, not a shortcut through it.
The partner of a British or settled person usually applies for a Spouse Visa, then for Indefinite Leave to Remain after the qualifying period, and only then for naturalisation as a British citizen. Each stage is a separate application with its own requirements and fee.
Can you work in the UK on a visitor visa?
No. A Standard Visitor Visa does not permit you to take employment or do paid work for a UK business, and working in breach of your conditions can lead to your leave being cancelled.
Visitors may carry out a limited set of permitted business activities, such as attending meetings or conferences, but these do not extend to filling a role or being paid by a UK employer. Anyone intending to work in the UK needs a route that allows it, such as the Skilled Worker Visa.
Do all visa holders get free NHS care?
No. Most people applying for a visa of more than six months must pay the Immigration Health Surcharge as part of the application, which gives access to the NHS on broadly the same basis as a resident.
As of June 2026, the surcharge is £1,035 per year for most applicants, and £776 per year for students, their dependants, people on the Youth Mobility Scheme, and applicants under 18, according to the GOV.UK healthcare surcharge guidance. Visitors do not pay the surcharge and are not entitled to free non-urgent NHS treatment, so travel insurance is sensible.
Can visa holders claim benefits and public funds?
No. Most people on a UK visa have a condition of no recourse to public funds, which means they cannot claim most benefits, including Universal Credit, Housing Benefit, and most forms of welfare support.
The list of restricted benefits is set out in the GOV.UK public funds guidance. The condition usually applies until you are granted settlement, so most people only access public funds once they hold Indefinite Leave to Remain or British citizenship.
Do you have to leave the UK to switch visa categories?
No, not usually. Many people can switch from one visa to another from inside the UK, without returning to their home country, provided they meet the requirements of the new route.
Common in-country switches include moving from a Student Visa to the Skilled Worker route, or from a fiancé visa to a Spouse Visa after marriage. Some routes cannot be switched from within the UK, including most visitor visas, where you would need to apply from outside the UK instead.
Can you apply for citizenship as soon as you get settled status?
Usually no. Most people must hold settlement, such as Indefinite Leave to Remain or settled status, for at least 12 months before they can apply to naturalise as a British citizen.
The main exception is for the spouse or civil partner of a British citizen, who can apply for naturalisation as soon as they hold settlement, without the 12-month wait. Every applicant must also meet the residence, good character, and Knowledge of Life in the UK requirements.
Is a child born in the UK automatically British?
No. A child born in the UK is British at birth only if, at the time of their birth, at least one parent is a British citizen or holds settled status such as Indefinite Leave to Remain.
A child born in the UK to parents who are not settled is not automatically British, but may be able to register as a British citizen later, for example once a parent settles or after the child has lived in the UK for the first ten years of their life.
Does ILR make you a British citizen?
No. Indefinite Leave to Remain is settlement, which lets you live and work in the UK without a time limit, but it is not citizenship. It does not give you a British passport or the right to vote in general elections.
Indefinite Leave to Remain can also be lost, usually after a continuous absence from the UK of two years or more. To become British, a person with settlement applies separately for naturalisation once they meet the requirements.
Is overstaying fine if you leave soon after?
No. There is no general grace period for overstaying, and the previous 28-day allowance for late applications was withdrawn. Remaining in the UK without valid leave is overstaying from the day your leave ends.
A limited exception allows an application made within 14 days of your leave expiring where there is a good reason, beyond your control, for the delay. Overstaying can affect future applications and lead to a re-entry ban, so it is far better to apply before your current leave ends.
Do you need an adviser, or can you just fill in the forms?
You can prepare an application yourself, but immigration applications are detailed, the requirements are precise, and fees are not refunded if an application is refused. A small error in evidence or category can be costly to put right.
A regulated immigration adviser checks that you are applying on the correct route, that your evidence meets the specified requirements, and that the application is made at the right time. This reduces the risk of a refusal on a point that could have been avoided.
Frequently Asked Questions
No. Marriage does not give an automatic right to live in the UK or British citizenship. The partner of a British or settled person applies for a Spouse Visa, then settlement, and then naturalisation, as separate stages.
As of June 2026, the surcharge is £1,035 per year for most applicants, and £776 per year for students, their dependants, Youth Mobility Scheme applicants, and under-18s. It is paid as part of the visa application and gives access to the NHS.
No, in most cases. Visitor visas generally cannot be switched into another route from inside the UK, so you would usually need to leave and apply from outside the UK on the route you want.
Overstaying begins the day your leave ends, as there is no general grace period. An application may be accepted within 14 days of expiry where there is a good reason beyond your control, but overstaying can harm future applications and lead to a re-entry ban.
