Certificate of naturalisation replacement

[souaden12]

Hello everyone.

Just wanted to ask if I apply for a duplicate of my citizenship certificate, how long does it normally take until they send me the replacement certificate?

I'm trying to apply for a passport renewal, and I need to include my naturalisation number and I think the issuing date as well.
If the replacement process takes long, is there a faster way of getting the information?

Thanks
