Immigration applications

Hi,

I have just received my ILR and now I am applying for citizenship as a wife of British Citizen.

On the application I am required to list all the visa applications I made.

I am not sure what to enter for this part:- 'Enter your reference number if known'

For Spouse Visa
Can I use the reference number on the BRP?
or should I use the Unique application Number? (I am unable to find this for the first round, but I have it for the second round and ILR)

Student and Visitor Visas

These were applied to more than 6 years ago so the only thing I have is rough dates and reference number on the visa sticker stuck to my passport. Will this be fine?

Thanks

It does states "if known". It is not mandatory to complete a reference number.

Hi Yes I am aware of that, I just want to make the application as complete as possible.

So am I ok in using the BRP and the Tier 4 visa reference numbers?

I want to only add these in if they are not wrong and can be used.

Thanks

It doesn't matter. UKVI have your full record anyway.
