regaring naturalisation

Hello every one.

I am applying for British Naturalisation next week. I have ILR.
I need to ask on form there is question ''have u made previous immigration application in the UK or abroad''
this include application for assylum.

Now , It says previous immigration , I am not sure answer would be yes or NO.
Second if I say yes then it ask when applied . I have been granted so many times tier2 , and granted ilr so do need to put all of those dates when applied for ILR and Tier 2

I will be grateful to you if you kindly answer to this

thanks

Yes you need to mention ALL previous UK immigration applications including ILR.
