I had the appointment the same day as you at 8 AM. My absences were 200 days in one calendar year but none >180 based on application date. I had to therefore submit a letter from employer in addition to P60s.
Application Form + Passport +BRP +Payment sheet+photos
Life in the UK pass notification letter
12 months payslips and Bankstatements
Old work permit papers (I was WP + Tier 1)
Points calculator output
cover letter to illustrate the split based on application date.
Photocopies of all the above.
The office has become a lot posh since I last visited for my Tier 1 extension... from a ticket counter to a consulting desk
I did not get a chance to speak to the case worker at all. They in fact did not ask for the photocopies. I offered it on my own and they accepted it.
I was slightly tensed in the preparation as my P60s for the first 2 years did not reflect HMRC employment history. But my company gave me confidence that the P60s are accurate so I did not submit the employment history letter.
I was quite surprised by the quick turn around actually...although I did not apply with any dependants...I came out at 8:45... 45 mins for ILR is incredible speed! The guy opening the door outside was surprised to see me coming out so fast. The letter they give after doesn't mention anywhere that ILR is granted. I was trusting the words of the person who gave the letter to me (I think she is the CW- she only said, your application has been successful and your BRP will reach your home address in a week. Please do not plan any travel meanwhile. I just said thank you and collected the letter and walked out...boring reply
I got my BRP today. Happy but more relief than happiness. I now subscribe to the thoughts some had on life after ILR...it isn't too different...
All the best to all those who are trying...happy to help
