How to Get UK Citizenship

The United Kingdom grants citizenship to hundreds of thousands of foreign nationals each year, and this figure has increased significantly in recent years. According to official Home Office statistics, 269,621 people were granted British citizenship in 2024. For comparison, the figure in 2020 was 130,568. This means that the number of naturalisations has effectively doubled within just a few years.

At the same time, although the process is clearly regulated, applicants face a considerable number of formal requirements. It is necessary to demonstrate a sufficient period of lawful residence, compliance with absence limits, English language proficiency, and successful completion of the Life in the UK test. Even minor errors in documents or dates can result in a refusal or a substantial delay in the application process.

In this article, we will explain in detail how the process of obtaining British citizenship works, what the main routes are, and what aspects require particular attention in order to improve the chances of a successful outcome.

How to Get UK Citizenship

In most cases, obtaining citizenship of the United Kingdom is a step-by-step legal process. The first stage is a visa that allows entry and residence in the country for a limited period based on a specific purpose such as employment, study, business activity, or family reunification.

The next stage is permanent residence, officially known as Indefinite Leave to Remain (ILR). This status means that a person is no longer subject to immigration restrictions. They can live and work in the UK without the need to extend a visa.

For citizens of the European Union and their family members, an alternative to ILR is permanent residence under the EU Settlement Scheme, known as settled status. In legal terms, it is equivalent to ILR and also allows the holder to apply for citizenship in the future.

The final stage is British citizenship. It provides the full set of rights, including:

• the ability to obtain a British passport;
• the right to vote;
• protection from losing status due to living outside the country.

The standard route involves five years of residence on a visa that leads to settlement. After that, ILR is obtained. In most cases, an additional twelve months of residence is required before applying for citizenship. This means that the total timeframe is approximately six years.

Routes to UK Citizenship Through Immigration Visas

The main way for foreign nationals to obtain UK citizenship is not a direct application for a passport, but a full immigration pathway. It begins with obtaining a visa that allows residence in the United Kingdom.

Skilled Worker Visa (UK)

The Skilled Worker visa is suitable for applicants who have a specific employer in the United Kingdom willing to provide sponsorship. The role must fall within the list of eligible occupations and correspond to an appropriate occupation code.

Mandatory requirements for the job and employer:

• The employer must hold a valid sponsor licence.
• The employer must issue a Certificate of Sponsorship (CoS), which specifies the job role, occupation code, employment conditions, salary, and duration.
• The position must meet the requirements of the relevant occupation code and the visa route.

The Skilled Worker route operates under a dual salary threshold. The salary must be at least £41,700 per year or the going rate for the occupation, whichever is higher. Even where concessions apply, the salary cannot be lower than £25,000 per year.

Requirements for the applicant:

• English language proficiency at a minimum of level B1. This can be demonstrated through an approved test, an academic qualification, or another accepted form of evidence, depending on the circumstances.
• Proof of maintenance funds of at least £1,270, unless the employer certifies maintenance on the Certificate of Sponsorship or an exemption applies.

A Skilled Worker visa is usually granted for up to five years and can be extended. To qualify for Indefinite Leave to Remain, the applicant must complete at least five years in this category. After obtaining ILR, a further twelve months is typically required before applying for citizenship.

Global Talent Visa (Recognised Talent)

The Global Talent visa is designed for specialists with a high level of professional achievement or proven potential in science, technology, engineering, humanities, arts, and culture.

The key requirement is recognition at the industry level. This is confirmed through an approval process officially referred to as an endorsement.

The Global Talent application process consists of two stages. The first stage involves obtaining an endorsement from a relevant organisation. Only after this can the applicant submit a visa application.

Endorsements are issued by authorised bodies depending on the field of activity:

• Science and medicine: Royal Society.
• Engineering: Royal Academy of Engineering.
• Humanities and social sciences: British Academy.
• Arts and culture: Arts Council England (including sub-organisations for film, architecture, and fashion).
• Research through grants: UK Research and Innovation (UKRI).
• Digital technology: designated Home Office endorsing bodies.

Each organisation applies its own assessment criteria, but the general principle remains the same. The applicant must demonstrate a significant contribution to their field or strong potential for future development.

Key requirements for applicants include:

• Evidence of achievements. This usually includes a portfolio, references, publications, projects, participation in major events, and commercial or academic results.
• Recommendation letters. At least three references from recognised experts in the field are required.
• Professional activity. The applicant must demonstrate ongoing engagement in their professional field.

The Global Talent route is considered an accelerated pathway. In certain scientific categories, it is possible to qualify for ILR after 3 years.

To apply for ILR under the Global Talent route, the applicant must:

• have lived in the UK for 3 to 5 years under this visa;
• demonstrate continued work in their professional field;
• pass the Life in the UK test;
• prove English language proficiency at a minimum of B1.

To qualify for ILR, the applicant must not have been absent from the UK for more than 180 days in any 12-month period during the qualifying period.

Unlike most immigration categories, this route does not require an employer and is not tied to a specific employment contract. The applicant can be employed, run a business, or work independently.

Innovator Founder Visa (Entrepreneur)

The Innovator Founder visa is designed for entrepreneurs who plan to establish and develop a business in the United Kingdom. It is not possible to apply for this visa without prior approval of the business project.

This approval is granted by authorised bodies, which assess three main criteria:

• Innovation. The business must not be a copy of existing solutions on the market. The applicant must demonstrate a unique offering or a significant improvement to a product or service.
• Viability. The applicant must have the skills, experience, and resources to implement the project. A business plan and financial projections are usually required.
• Scalability. The project must have growth potential, including the creation of jobs and expansion into wider markets.

Without meeting these criteria, endorsement cannot be obtained, even if the applicant has prior business experience.

Requirements for the applicant:

• The applicant must be actively involved in managing the business. Passive investment is not permitted.
• English language proficiency must be at least B2 under the CEFR scale or an equivalent qualification must be provided.
• There is no formal minimum investment requirement. However, the applicant must demonstrate sufficient funds to establish and develop the business, as well as to support themselves.

The Innovator Founder visa is granted for up to 3 years and does not require a standard extension. Instead, the applicant may apply for settlement at the end of this period, provided that the business is developing in line with the approved plan.

During the validity of the visa, the entrepreneur must maintain contact with the endorsing body and undergo regular progress assessments.

For ILR, the applicant must not be absent from the UK for more than 180 days in any 12-month period and must genuinely reside in the country and manage the business from within the United Kingdom. After obtaining ILR and residing in the UK for one year, the applicant can apply for citizenship through naturalisation.

UK Family Visa (Partner Visa)

The family visa is intended for spouses, civil partners, and unmarried partners of British citizens or individuals with settled status.

Key requirements:

• Proof of relationship through a marriage certificate or civil partnership registration.
• Evidence of living together.
• Supporting documents such as correspondence, joint travel, and financial records.

The sponsoring partner must be a British citizen or hold Indefinite Leave to Remain (ILR). For EU citizens, settled status is sufficient. Both applicants must confirm their intention to live together in the United Kingdom.

Financial requirements mean that the sponsor must have an income of at least £29,000 per year. If the income is below the required threshold, savings can be used instead.

At the initial stage, a basic level of English at A1 is required. When extending the visa, the required level increases, and at the stage of applying for settlement, a B1 level is usually required.

The family visa is typically granted under a 5-year route, which is divided into two stages. The initial visa is issued for 2 years and 9 months, and it is then extended for a further 2 years and 6 months. The total residence period is 5 years, which is required to apply for ILR.

After obtaining ILR, a spouse or partner of a British citizen can apply for citizenship without the additional 12-month waiting period.

Studying in the UK: How to Get Citizenship Through a Student Visa

A student visa is suitable for those who plan to study in the United Kingdom and then remain in the country for work and further immigration. This route is not direct and is used as a first step, after which it is necessary to switch to a visa category that leads to settlement.

Main requirements for a student visa:

• Confirmation of acceptance. The educational institution must hold a licence to sponsor international students and issue a Confirmation of Acceptance for Studies (CAS).
• Financial funds. The applicant must demonstrate sufficient funds to cover tuition fees and living expenses.

The minimum maintenance requirement is £1,334 per month for study in London and £1,023 per month outside London. The funds must be held in an account for 9 months of study.

The student visa has several significant limitations:

• limited working hours during studies;
• the time spent on this visa does not count towards the standard 5-year period for ILR;
• no direct pathway to settlement.

This means that to obtain citizenship, it is necessary to switch to another immigration route. After completing their studies, applicants can apply for permission to stay under the Graduate visa. The main conditions are completion of an accredited programme and being in the United Kingdom at the time of application.

The Graduate visa is granted for 2 to 3 years and allows the holder to work without being tied to a specific employer or salary level. However, time spent under the Graduate visa does not count towards ILR. To continue the immigration pathway, it is necessary to switch to a visa that leads to ILR, most commonly the Skilled Worker route.

Permanent Residence in the UK (Indefinite Leave to Remain, ILR)

Indefinite Leave to Remain (ILR) is a form of permanent residence in the United Kingdom. Once it is granted, the applicant is no longer subject to time restrictions on their stay, and there is no need to extend their immigration status. In essence, ILR is the transition point between temporary residence and citizenship.

This status allows a person to live and work in the UK without restrictions, change employers without notifying the immigration authorities, engage in business activities, and access public services, including the healthcare system. However, ILR can be lost if the person remains outside the United Kingdom for more than two consecutive years or in cases of serious legal violations.

The timeframe for obtaining ILR depends on the immigration category. The standard requirement is 5 years of residence under a qualifying visa. Accelerated routes exist in limited categories where the UK aims to attract specific professionals or investment.

Continuous residence is one of the most important factors when an application is assessed. The main rule is that the applicant must not be absent from the United Kingdom for more than 180 days in any 12-month period during the qualifying period.

Only full days of absence are counted. The day of departure from the UK and the day of return are usually not included in the total. However, even with accurate calculations, exceeding the limit can reset the qualifying residence period.

To obtain ILR, the applicant must:

• demonstrate English language proficiency at a minimum of level B1. This can be confirmed through an approved language test, a degree taught in English, or another document accepted by the immigration authorities;
• pass the Life in the UK test. This exam consists of 24 questions covering the country’s history, political system, and social structure.

ILR Costs and Related Expenses

Obtaining ILR involves significant financial costs. The government application fee is £3,029 per applicant. This fee is non-refundable in the event of a refusal.

Additional costs may include:

• taking the Life in the UK test;
• proving English language proficiency;
• translation and preparation of documents;
• legal assistance, if required.

Priority processing services are also available. Depending on the category, a decision can be received within a few days or even one working day for an additional fee of £1,000.

The standard processing time is up to six months. During this period, the applicant retains the right to remain in the UK based on the submitted application.

An application for ILR can be submitted no earlier than 28 days before reaching the required qualifying period. Submitting earlier than this will result in a refusal without substantive consideration.

UK Citizenship Through Naturalisation

Naturalisation is the main route to obtaining UK citizenship for foreign nationals. Unlike citizenship by birth or descent, this process requires the applicant to have lived in the United Kingdom for a significant period of time and to be integrated into society.

The key requirement is holding permanent status. In most cases, this means Indefinite Leave to Remain (ILR) or settled status.

Requirements for the qualifying residence period:

• residence in the United Kingdom for at least 5 years;
• holding ILR or settled status;
• residence for at least 12 months after obtaining permanent status.

This means that the minimum period before applying for citizenship is typically 6 years.

For spouses and civil partners of British citizens, it is sufficient to have lived in the UK for 3 years and hold ILR or settled status. In this case, there is no requirement to wait 12 months after obtaining ILR.

Absence requirements for the 5-year route are no more than 450 days outside the UK during the last 5 years and no more than 90 days during the last 12 months.

For the 3-year route through marriage, the limits are no more than 270 days over 3 years and no more than 90 days in the last year.

An additional mandatory requirement is physical presence in the UK at the start of the qualifying period. This means that the applicant must have been in the United Kingdom exactly 5 years before the application date, or 3 years for spouses.

Requirements for naturalisation applicants:

• demonstrate English language proficiency at a minimum of level B1 by passing an approved test or providing a degree taught in English;
• pass the Life in the UK test. It does not need to be retaken if it was already passed for ILR;
• meet the good character requirement. The authorities assess criminal history, compliance with tax obligations, financial conduct, the accuracy of the information provided, and compliance with immigration rules.

The standard processing time is up to 6 months. In some cases, the process may take longer if additional checks of documents or the applicant’s background are required. There is no priority processing service for citizenship applications.

Cost of UK Citizenship in 2026

The cost of obtaining UK citizenship is made up of several stages. Under a standard scenario, the total budget can range from £8,000 to £13,000 per person, excluding additional expenses.

Main government fees:

In practice, the Immigration Health Surcharge accounts for a significant portion of the total cost, especially for 5-year routes.

In addition to government fees, applicants face additional expenses that can substantially increase the overall budget.

Additional costs when applying for UK citizenship:

These costs are not legally required, but in practice they arise in most cases.
