Most ppl have written about thte documentation needed, so I wont repeat that. Some of my other experiences here:
- I attended with my 1.5 year old baby and she totally refused to get photographed for biometrics. We ended up creating a scene there

- Afte rbiometrics, a case worker called me to a counter and asked me to give all my documents. She didnt ask anything in particular, but just said give all originals + xerox. she then handed it over to another worker, who probably worked on it. She told me to come back in few hours.
- I went out and came back in two hours and my file was done. She said ILR approved and I would get the BRP in few days.
- I then received 9 mails from ukba for the appointment confirmation for the same appointment I had finished attending!! Just ignored those mails.
overall, it was a good experience for me and was less hassel than what i had thought.
