If you meet the eligibility criteria, you can apply for ILR by completing the appropriate application form and submitting it to the Home Office. You may also need to provide supporting documentation, such as your passport, proof of your immigration status, evidence of your financial situation, and your Life in the UK test certificate.

1. If you had indefinite leave to remain, go back to the UK
If you have been living in the UK for a considerable period of time and wish to continue residing there for
an indefinite period, you may be eligible to apply for indefinite leave to remain (ILR). ILR is also
commonly referred to as permanent residency, as it allows you to live and work in the UK without any time
limits or restrictions.
To be eligible for ILR, you must meet specific requirements set out by the Home Office, which
include:
1.Length of stay: You must have lived in the UK continuously for a specified period of time,
typically five years.
2.Immigration status: You must have been in the UK on a qualifying visa, such as a work visa,
student visa, or family visa, for the entire duration of your stay.
3.Financial requirements: You must meet specific financial criteria, which may include
earning a certain income or having a certain amount of savings.
4.English language skills: You must demonstrate that you have a certain level of proficiency in
the English language.
5.Life in the UK test: You must pass the Life in the UK test, which assesses your knowledge of
British history, culture, and values.

2. If you meet the eligibility criteria, you can apply for ILR by completing the appropriate application form and submitting it to
the Home Office. You may also need to provide supporting documentation, such as your passport, proof of your
immigration status, evidence of your financial situation, and your Life in the UK test certificate.
The Home Office will then review your application and assess whether you meet the eligibility criteria for ILR. If your
application is approved, you will receive a biometric residence permit (BRP) that will allow you to live and work in the UK
without any restrictions.
It's important to note that ILR does not grant you British citizenship, but it does give you the right to apply for citizenship
after a certain period of time. Additionally, if you leave the UK for an extended period, you may lose your ILR status, so it's
essential to keep track of your travel and ensure that you meet the residency requirements.
In conclusion, applying for indefinite leave to remain can be a lengthy and complex process, but it's essential if you wish to
continue living and working in the UK for an indefinite period. If you are considering applying for ILR, it's crucial to
familiarize yourself with the eligibility criteria and requirements and seek professional advice if necessary. With the right
preparation and documentation, you can increase your chances of success and achieve permanent residency in the UK.
