Spouse visa late entry date

[Azizdjerroud]

Hi,
I'm a bit confused with regards to the next move for my spouse visa.
First spouse visa valid from the 16/06/2015 to 16/03/2018.
Entry date to UK : 22/09/2015.
Visa extension approved and valid from 02/03/2018 to 16/09/2020.
Looks like, I cannot mathematically spend 05 years in UK, unless the duration is calculated from the date of the visa not the entry.
Do I need to extend my stay to complete the required 05 years ?
When I qualify to apply for ILR ?
Thanks for your help.
Kind regards

Hi,
Thanks for your quick reply.
Spouse visa 05 years route. Partner of a british citizen . I have used Set (M) form for my extention.
Thanks for your support.

You form FLR M for en extension. Form SET M is for ilr.

Your spouse qualifies for ilr no sooner than within 28 days before the 5th anniversary of the date she entered the UK, so 22/9/20 minus 28 days.

There is no requirement to have a valid visa right up to the 5 year mark.

Thanks, I have on this case a window of approx days (between 24/08/2020 to 15/09/2020) to apply.
Thank you again for your quick reply and help.
Kind regards,

Date of application is the date you submit and pay online. So you should be fine.

Don't forget English B1 and LIUK tests.
