Hi Zimba. I'm very Lucky to come across your page. i have this bothering me and I'm very confused.
I'm on Tier 2 skilled worker Visa (Health and Care).

Please, the date on my
Vignette sticker is 18/10/2018
Date of arrival to UK is 01/11/2018,
date on my Ist BRP is 24/10/2018
My current visa/Brp will expire on 23/10/2023.
Please what is the earliest i can submit application for my ILR?
