Naturalisation Eligibility

Dear All,
I arrived in the UK in 2016 to begin my PhD studies. After completing my PhD, I worked as a Research Fellow for one year before leaving the UK on 3 December 2021. My visa expired on 14 December 2021. I then returned to the UK on 5 April 2022 to take up another position, using a new entry clearance vignette.

As per your previous advice, I understood that this period would break continuous residence for ILR purposes, and I followed your guidance accordingly. I have now been granted Indefinite Leave to Remain (ILR) through the Global Talent route, effective from 14 March 2025, after completing the required 3 years.

I have an enquiry that I would appreciate your clarification on:

Naturalisation eligibility: I am planning to apply for British naturalisation next March. I meet all the requirements, including:

Absences from the UK in the last five years are well below the 450-day limit.

I will have held ILR for 12 months by the time of application.

I have not breached any immigration laws, including overstaying.

My concern is whether the four-month period I spent outside the UK between December 2021 and April 2022—during which my previous visa had expired—would be considered a break in residence and affect my eligibility for naturalisation, even though I have not breached any immigration laws, such as overstaying, because I understand that lawful residence differs from continuous residence for ILR.
Would this require me to start a new five-year qualifying period from April 2022, or is the naturalisation assessment different from ILR, meaning I would still be eligible to apply next March?

There is no continuous residence requirement for citizenship, it's an entirely different process than ILR. You will be able to apply in March.

What does lawful residence mean?

You are lawfully residing in the UK if you have permission from the Home Office, via visas and ILR.

Thank you for your response. I am lawfully residing, and there is no continuous residence requirement. However, according to various AI research tools, it appears I would need to remain for 5 years, similar to the ILR requirement, in order to avoid the risk of my naturalisation application being refused, which means I still have to stay for two more years before applying for citizenship

I would avoid consulting AI on immigration & naturalisation topics. The outputs are not validated!

What is your immigration history?
For naturalisation you need ILR which normally takes 5 years to gain.
Once you have ILR there's a wait period of 12 months before applying, if you are not married to a British citizen, otherwise you could apply once you gained ILR.

5 years from the beginning of the qualifying period to the date you apply, including one year on ILR. I would absolutely advise against following any AI generated advice on immigration/citizenship matters.

I was granted ILR after 3 years under the Global Talent route. From August 2016 to December 2021, I had spent 5 years in the UK, though I travelled to my home country for 4 months before applying for a new visa from abroad and returning in April 2022. I understand that this break reset my continuous residence from April 2022. However, from your explanation, it seems that naturalisation is based on lawful residence rather than continuous residence, unlike ILR

That is correct. Once ILR is obtained, constraints on continuous residence stop applying to be eligible for citizenship.
