Does Marrying a British Citizen Give You Automatic Citizenship?
Getting married to a British national or settled person does not automatically grant you citizenship in the United Kingdom. In fact, to become a UK national, you must first submit your Spouse Visa application and meet several eligibility requirements which may be based on your immigration history and current situation.
Before you become a citizen of the UK, you must have held Indefinite Leave to Remain in this country for at least three years.
IAS’ immigration attorneys are experienced in British residency applications and have already helped several clients submit successful requests. Get in touch with our team of professionals to learn more about your options to apply for UK British Citizenship by Marriage from South Africa.
How to Apply for British Citizenship by Marriage: Step-by-Step Process
You can submit your application for British citizen for South Africans online, by filling in the form AN.
Once your request is submitted, you need to pay your application fees and book an appointment at the nearest UK Visa and Citizen Application Services (UKVCAS). Here, your biometric details (fingerprints and photos) will be collected. Besides, you will be able to scan a copy of any additional documents that you wish to attach to your application.
If you don’t wish to apply online, you can submit your paper form. If you need further assistance, you can get in touch with our UK immigration attorneys.

From Spouse Visa to ILR: Your Route to Settlement Before Citizenship
To qualify for British citizenship for South African nationals, you must first have lived in the UK for at least three years as a settled person.
Holding Indefinite Leave to Remain is one of the mandatory and preliminary steps to become a national of the United Kingdom.
By getting Indefinite Leave to Remain, you will be able to live, work and study in the UK free from any immigration restrictions. To qualify, you must demonstrate your English fluency and pass the Life in the UK test.
If you wish to apply for ILR through marriage, you may need to follow different immigration paths and the eligibility criteria may vary. Speak to our team of UK immigration experts to find out more.
British Citizenship Residency Requirements: The 3-Year Rule Explained
Gov.uk requires you to prove you were physically present in the UK exactly three years before the Home Office receives your application, in addition to meeting the absence limits below.:
- Spent more than 270 days outside the UK during the three-year qualifying period before your application
- Spent more than 90 days abroad in the last 12 months before you submit your forms
Most importantly, you must not have broken any UK immigration law at any time during your residency in the UK.
Good Character Requirement for British Citizenship by Marriage (2026 Rules)
To prove your “good character” and qualify for British citizenship, you must have always respected UK law and fulfilled all your obligations as a residence since the day you arrived in this country.
Under current Home Office guidance, a custodial sentence of 12 months or more will normally lead to refusal, and a sentence of 4 years or more is treated as a permanent bar. Since 10 February 2025, anyone who previously entered the UK illegally will normally be refused citizenship regardless of how long ago this happened; other immigration breaches are usually assessed over the last 10 years.
The British Citizenship Ceremony: What to Expect and How to Prepare
Applicants who have acquired British citizenship and are aged 18 or over, will be invited to attend a proper ceremony at the end of their application process.
You must book your ceremony within three months of receiving your invitation from the Home Office. The even will then be organized by your local council. The cost of this ceremony is £130 but this is typically included in your application.
If you are currently outside the UK, you can ask the UK embassy or consulate in South Africa if you can have your ceremony there.

Frequently Asked Questions
It costs £1,839 to apply for British nationality through marriage (British citizenship by naturalisation) as a South African.
However, they may be additional fees related to your application. This includes having your biometric information collected, the cost of your English language and Life in the UK tests, and the translations of any supporting document which is not written in English or Welsh (if needed).
Once you have submitted your request, the Home Office will need up to 6 months to review your case and disclose its response.
If you fail to provide relevant supporting documents or to fill in your form properly, your case may be delayed or even refused.
For this reason, it is advisable to seek the assistance of a professional UK immigration expert. Get in touch with IAS to learn more about our services for South African citizens.
Unfortunately, you cannot follow this UK residency route if your partner died before you submit your application.
However, if you already hold ILR, you may be eligible for UK nationality through naturalization or other immigration routes.
Once you receive British nationality through marriage or naturalization, you can apply for your first UK adult passport.
This document will be valid for ten years and can be used to demonstrate your status as a citizen of the United Kingdom when travelling abroad or within the UK.
Not automatically — you need a Spouse Visa first. Marriage itself doesn’t grant a right of residence; the visa does, and it’s the route that eventually leads to ILR and then citizenship.
A child born in the UK is automatically British only if one parent is already a British citizen or holds settled status at the time of the birth — not simply because a parent is in the citizenship application process. Worth a short, clearly sourced answer linking to gov.uk’s child-citizenship checker.
