Stricter Rules for British Citizenship Applicants From 2025

Starting 10 February 2025, new changes to the “good character” requirement will make it significantly harder for individuals who entered the United Kingdom (UK) illegally to become British citizens. Under the updated rules, any applicant who entered the UK unlawfully will typically be refused citizenship, regardless of how much time has passed since their illegal entry.

This marks a major shift in the naturalisation process, as prior to this change, the Home Office had discretion to overlook past immigration infractions in some cases.

For those submitting applications before 10 February 2025, the Home Office will still assess whether an applicant's illegal entry should be disregarded in the character assessment. However, after the cut-off date, the stricter stance will apply universally, leaving little room for exceptions.

Understanding the Good Character Requirement

The “good character” requirement is a crucial element of the British naturalisation process. It applies to all applicants aged 10 or older and is designed to ensure that those granted citizenship respect the laws and values of the UK.

Failure to meet this requirement can result in an outright refusal of a citizenship application, with very limited opportunities for appeal.

The Home Office evaluates an applicant’s character by considering factors such as:

Criminal history, including custodial sentences and repeat offences
Financial conduct, including unpaid debts and bankruptcy
Involvement in terrorism or international crimes
Deception, dishonesty, or fraud (e.g., benefit fraud or false information on immigration applications)
Breaches of immigration laws, including illegal entry or overstaying a visa

Key Impacts on Future Applicants

1. Illegal Entry Will Be a Permanent Barrier

Previously, individuals who had entered the UK illegally but later established legal status and integrated into society had a chance to naturalise. From 10 February 2025, this will no longer be the case. Anyone who arrived illegally will likely face automatic rejection, even if they have since become law-abiding residents.

2. No Right to Appeal in Most Cases

Applicants refused on good character grounds generally have no right to appeal, making it crucial to ensure full compliance with the updated rules before submitting an application. This means that those with past immigration breaches should consider legal advice before applying.

3. Greater Scrutiny of Immigration History

With the focus shifting towards stricter enforcement, applicants with any past breaches of immigration law—including working without permission, overstaying a visa, or hiring illegal workers—may also face increased scrutiny. The Home Office has the discretion to refuse citizenship based on a history of non-compliance with visa conditions.

4. Stronger Emphasis on Criminal Records

Under the changes introduced in 2023, applicants with a custodial sentence of 12 months or more will automatically be refused citizenship. This applies to sentences served in the UK or overseas. The new 2025 rule further reinforces this by eliminating discretionary leniency for those who have committed immigration-related offences.

What This Means for Those Seeking British Citizenship

If you're applying for British citizenship, assess your eligibility under the updated good character rules. If you have immigration violations, seek professional advice. Ensure your application reflects compliance with UK laws and values, and be transparent about your history.

If you are unsure about how the new rules impact you, consulting an immigration lawyer can help clarify your position and identify potential solutions before you apply. The stricter rules mean that careful preparation is now key to a successful British citizenship application.

Applying for British citizenship costs £1,605 per adult. If refused, a reconsideration request costs £450 (refundable if successful). If that fails, the only option is Judicial Review, which requires legal advice and can cost thousands. Given these high costs and limited appeal options, many may be effectively excluded from applying unless the guidance changes.
