Hi,
I'm in a similar situation - I applied for Canadian citizenship for myself and my two chidren who are under 14 years old, and I received the invites to take the oath on Oct 4th. I live in Canada, but the children are abroad and were not planning to return to Canada anytime soon, so I was wondering if only I can attend the oath ceremony in Canada, while the children will remain abroad and won't attend the oath ceremony. After I get the citizenship certificates, I will apply for passport for myself (here in Canada). For the children, I guess I can apply for their passports either here (not sure if that's possible without them being here), or their mother can apply for them abroad in the Canadian embassy. I understand this can take time and they won't be able to return to Canada until they get the passports, but I'm ok with that. Also I guess that in an emergency there are several ways to travel to Canada even without a passport - temporary passport, emergency authorization, or entry at the land border with the citizenship certificates.
Can you please let me know if this there is anything wrong with my understanding.
