Earliest Date eligible for ILR

[India_123]

Hi All,

I am on Tier 2 general visa and will be completing 5 years in July this year. I have a query on what is the earliest date I am eligible to apply for ILR. From the two dates listed below, which one should I consider

1. I switched from Tier 2 ICT to Tier to general with in UK. My visa was issued on May 20th 2016 (issued on date in Tier 2 general BRP is 20th May 2016)
2. My actual work start date in my COS for Tier 2 general visa was 20th July 2016. So from 20th May 2016 to 20th July2016, I was serving notice period with my old employer but I was still in UK and never went outside UK.

My doubt is, will I be eligible for ILR this April (28 days before 20th May as per visa issue date) or I will be able to apply only on June (28 days before 20th July as per my work start date)?

Thanks in advance.

Visa issue date is used. Your work start date is irrelevant
