How long must I wait before applying for citizenship as a spouse?

You must have lived in the UK for at least 3 years before your application date. You must also hold ILR (Indefinite Leave to Remain) at the time of application. Unlike general naturalisation, there is no requirement to have held ILR for 12 months — you can apply as soon as you receive ILR, provided you meet the 3-year residency requirement.

Do I need to still be married when I apply for citizenship?

Yes. You must still be married to or in a civil partnership with a British citizen at the time you apply. If you have divorced or your partner has died, you will need to apply under the general naturalisation route (Section 6(1)) instead, which requires 5 years of residence and 12 months of ILR.

How many days can I be absent from the UK?

As a spouse applying under Section 6(2), you must not have been absent from the UK for more than 270 days in the 3-year qualifying period, and not more than 90 days in the 12 months immediately before your application. These limits are strict but the Home Secretary can exercise discretion to overlook minor excesses.

Can I apply for citizenship before getting ILR?

No. You must hold ILR before you can apply for citizenship. Most people on the Spouse visa route get ILR after 5 years. However, the citizenship application itself only requires 3 years of residence, so you can typically apply for citizenship very soon after receiving ILR.

What is the total timeline from Spouse visa to citizenship?

The typical timeline is: Year 0 — arrive on Spouse visa. Year 2.5 — extend Spouse visa. Year 5 — apply for ILR. Year 5+ — apply for citizenship (once ILR is granted). The total is approximately 5 to 6 years from your first arrival to becoming a British citizen.

Citizenship for Spouses of British Citizens

Spouses of British citizens can apply for citizenship after just 3 years of UK residence (compared to 5 years for the general route) and do not need to wait 12 months after receiving ILR. This guide covers the full process from Spouse visa to British citizenship.

The Spouse Route to Citizenship

British nationality law provides a faster path to citizenship through naturalisation for people who are married to or in a civil partnership with a British citizen. This is set out in Section 6(2) of the British Nationality Act 1981.

The key advantages over the general naturalisation route are:

A shorter residency requirement: 3 years instead of 5
No requirement to wait 12 months after receiving ILR
A more generous absence allowance: 270 days over 3 years instead of 450 days over 5 years

These benefits recognise the close connection to the UK that comes through marriage to a British citizen.

Eligibility Requirements

To apply for citizenship as a spouse under Section 6(2), you must:

Be aged 18 or over
Be married to or in a civil partnership with a British citizen
Hold Indefinite Leave to Remain, EU Settled Status, or another form of settled status
Have been resident in the UK for at least 3 years before the date of your application
Not have been absent from the UK for more than 270 days in those 3 years
Not have been absent for more than 90 days in the 12 months before your application
Have passed the Life in the UK test
Meet the English language requirement
Be of good character

Note that you must still be married at the time of application. If your marriage has ended through divorce or your spouse has passed away, you apply under the general route (Section 6(1)) instead, which requires 5 years of residence and 12 months of ILR.

The Full Timeline

Here is how the journey from Spouse visa to citizenship typically works:

Year 0: Arrive in the UK on a Spouse visa (valid for 33 months).
Year 2.5: Apply to extend your Spouse visa (for another 30 months).
Year 5: Apply for ILR using SET(M).
Year 5+: Once ILR is granted, apply for citizenship immediately (no 12-month wait). You will have had more than 3 years of residence by this point.

In practice, the citizenship application takes about 6 months to process. So the total time from first arrival to holding a British passport is approximately 5.5 to 6 years.

The ILR Step

You cannot skip ILR and go straight to citizenship. ILR is a prerequisite. Most people on the Spouse visa route apply for ILR after 5 years using the SET(M) form.

The ILR application requires you to meet the financial requirement again, provide evidence of your ongoing relationship, and pass the English language requirement at B1 level (higher than the A1 level required for the initial Spouse visa).

The ILR fee is £2,885. See our ILR cost breakdown for details.

Counting Your Absences

The absence limits for spouses are:

No more than 270 days absent from the UK in the 3 years before your application
No more than 90 days absent in the 12 months immediately before your application

These are calendar days, not working days. The day you leave the UK and the day you return both count as days of absence. Keep accurate records of your travel dates.

If you have exceeded the limits, you can still apply and ask the Home Secretary to exercise discretion. This is more likely to be granted if the excess is small and there were good reasons for the absences (such as a family emergency). However, significant excess will usually result in refusal.

Good Character for Spouses

The good character requirement applies to all citizenship applications, including those by spouses. You must disclose any criminal convictions, cautions, or other matters that may affect your character assessment.

Being married to a British citizen does not give you any advantage in the good character assessment. The same standards apply as for any other applicant. See our citizenship refusal reasons guide for more information.

What If Your Marriage Ends?

If your marriage ends before you apply for citizenship, you cannot use the spouse route. You will need to apply under the general naturalisation route (Section 6(1)), which requires:

5 years of residence instead of 3
12 months of ILR before applying
No more than 450 days absent in 5 years

If your marriage ends after you submit your citizenship application but before a decision is made, you should inform the Home Office. The application may still be considered under Section 6(2) if you were married at the date of application.

If your marriage ends before you have received ILR, this could also affect your immigration status. You may be able to remain on the family route as a victim of domestic violence or in the interests of any children. Seek legal advice if you are in this situation.

The Application Process

The application is made using Form AN, the same form used for all naturalisation applications. The form is completed online.

You need to provide:

Your passport and BRP
Your marriage or civil partnership certificate
Your partner's British passport or naturalisation certificate
Life in the UK test pass notification
English language evidence
Details of two referees
Details of your absences from the UK

The fee is £1,344. Processing typically takes about 6 months. If approved, you attend a citizenship ceremony to receive your certificate of naturalisation.
