So I'm applying for my Naturalisation application and I have come across the questions where it asks me about my previous entry clearance applications.

I was on tier 4 student visas for couple of years and later applied for unmarried partner visa and settled status.

Currently, they are asking me about the reference numbers and the dates of the biometric finger prints , I currently do not have that information so what should I do in this scenario?

Though I do have my previous BRP numbers but I don't have the dates on which my fingerprints were taken and reference number of the application I applied before.

I will very much appreciate your help gurus.

Provide all details you can remember, including approx. dates and the BRP numbers. Explain in a covering note that the info you are providing is as far as you can remember. It is not a deal breaker, won't lead to a refusal.
