(1) I and some of my children will be eligible for citizenship in a few weeks time. We got stamp 4 at the same time. However, in form 11 for child and form 8 for me, my original passport is required, and you know child's application must be sent to a different address from where I have to send my application, though it is in the same location but different address, so i can only provide my original passport for either for child's application or for myself, and we want to apply at the same time. I am confused here.

(2) It would be difficult for me to get the original 3 different proof of address like utility bills for all children applIcations as I only have for myself. what do you think? Please note- I am not seeking legal advice. Thanks.
(3) Does the Three different proofs of residence for each year of residence claimed has to be a recent date like 2019, can use old utility bills from the year I was granted residency?
(4) Can I use foreign Attestation of Birth that has been authenticated by my Country's Consulate in Ireland?
