*** First and foremost, apologies

I was issued a Tier 2 General visa in Sep 2017 and eligible for ILR in Sep 2022. Details below:
- Vignette affixed on passport and valid from 12th Sep 2017 to 12th Oct 2017
- Entry into UK: 22th Sep 2017
- 1st BRP (sponsored by 1st ex-employer): 29th Sep 2017 to 02nd Oct 2022
- 2nd BRP (sponsored by 2nd ex-employer): 18th Sep 2019 to 29th Sep 2022
- 3rd BRP (sponsored by current employer): 07th April 2021 to 14th Jan 2023
- No prolonged absences
1. How early can I start my ILR application?
2. How early can/should I submit the ILR application?
3. How early can/should I pay for the ILR application?
4. How early can/should I book the appointment date?
5. How early can/should I take the appointment date FOR (assuming dates are available)?
This post may be unusually a very early one (given my dates) but I hope you agree that its never too early to be self aware of any situation
