Apologies if this has been asked before, I have seen people making this assumption but no one appears to have commented / corrected on this in the past:
My situation:
Tier 2 / Skilled Worker Visa
VISA No. 1
UK Entry Clearance Valid from 26/08/18 to the 25/09/18
Entry Stamp 10/09/18
BRP Date of Issue 30/08/18
BRP Expiry 16/09/21
VISA No. 2
BRP Date of Issue 01/10/21
BRP Expiry 23/09/24 (The Immigration Advisor accidently applied for 3 years

So the question is when can I apply for ILR?
28 Days prior to Entry Clearance, Entry Stamp or Date of BRP Issue?
If I apply for priority, theoretically I will get ILR prior to 5 years, is that okay?
Cheers
