More questions about naturalisation app....

[Wisco]

Hoping someone out there can help.
Am in the process of filling out my citizenship application and have a couple questions.
1. I went to university here part time while working although the purpose of my visa was not to study (I am/was on stamp 4 at the time)- do I put my dates of study on the application? My original thought was that it's incidental and doesn't need to go on there ( I know they exclude time spent on a study visa as part of your 5 years but that wasn't the case for me)
2. Which tax form are they looking for in the checklist of things to send with your application- will a certificate of tax credits suffice?
3. Should I include a copy of my first GNIB card as well? (If I can find it, that is....)
Thanks in advance for any help!

1. you do not need to include studying time, as you were not on stamp 2.
2. P21 from revenue
3. yes , include GNIB card (copy), that's a must
