thanks,,,It was a very simple and easy process. They send you an email with instructions and things to keep by the side during oath that includes PR card, 2 pieces of IDs, a pair of scissors, a pen and a printed oath form. You have to cut the PR card and sign the oath form infront of them which you scan and email them. They told they'd send the citizenship certificate within 2 weeks. I received mine today within 1 week.
Hope this helps
