I got my ILR approved on 17 of feb
my experience :
book online appoinment for 17/02 exactly 28 days before due date at 10:30
Arrive croydon at 9:15 and was allowed in for security around 9:40
normal security check and then waited in que for 25 mins
Went to window for initial screening of documents . Quite straight forward gentleman at the desk in 'to the point' conversation mode and not ready to listen anything else

Then was send to first floor to make payment. Quite polite and help lady.
Went to second floor and wait for my number to call. After 30 mins my number was called.
I was ask for the following docs:
1. Application form
2. Payment receipt
3. Letter from initial screening officer
4. Letter from current employer ( Must )
5. Last three month payslips
5A. Bank Statement
6. P45 or Letter from previous employer or P60
( I gave P45 and he didn't ask for rest of documents )
7. Passport
8. Photographs
9.Ticket Number ( Reference number )
after reviewing documents. He said the rest of the docs are in order and he is waiting for some further information from the system and i might have to wait for 2 hrs and i can go out and check the status of my application from first floor at customer services windows on return.
I went out and come back after 1 hours and then wait for an hour till my number was called and customer services office told me that my application is successful and ask me to check my detail on visa
Pleasant experience. Very helpful attitude .
Thank you everyone for you support and guidance.
Regards
