Earliest to submit/apply for ILR

Hi everyone. Hope you are well.

I am a bit confused as I have read and heard different things about when we can apply for ILR.

- My partners initial spouse visa BRP had issue date of 17 Aug 2020
- She entered UK on 02 Oct 2020

I wanted to seek clarification on what date is the earliest she can apply for ILR from below?

1) 28 days before she hits 5 years in UK (counted from the date of entry in UK - 02 Oct 2020)

2) 28 days before she hits 5 years in UK (counted from the issue date on initial BRP - 17 Aug 2020)

3) 28 days before the FLR BRP expires - 02 Jan 2026

I appreciate your help and look forward to your responses.

Kind Regards
Shyam

It is number 1.

Thanks, does this 5 year period include time waiting and between applications?

I.e.
- Initial spouse visa BRP had Date of Expiry - 25 May 2023
- FLR extension BRP has Date of Issue - 14 June 2023

Kind Regards
Shyam

Yes it does, provided an extension application eas made before the last visa expired.
