Hello, I am applying for UK Citizenship soon, as I have had ILR for 6 years (ILR was achieved via the 10 years long residency route, with a combination of student and work visas).

The UK citizenship application asks for the application dates and reference numbers of all my previous visas, and I don't have this information for some of them. I have the visa stamps in my previous passport and Work and student visa card reference numbers, but not the actual dates of application etc.

Will there be an issue with my application?

Many thanks in advance.

In relation to the dates and reference numbers, the questions state 'if known'. So if you don't know, you don't need to answer.
