Previous application missing details

[clicosean]

Hi all,

I'm applying for naturalisation under 10 year + 1y ILR. There is a section of asking about all my previous visa application. However, I only have details up to 2016. I can't remember my previous details of my applications so would I be alright to just ignore the dates? and just answer how many time I applied for it instead?

With reference number, could I give them my vignette number instead?

Thank you in advance

Provide the details you/remember, including any reference numbers.
Some of the fields are "if known". It's not an issue.
You could explain further on a covering note if you wish.
