Thank you for your reply.
Situation is bit complex then I mentioned above. We are outside Canada. Please advise what should be our way forward ...
1. Provide Solemn declaration after 6 weeks ( can I give it from outside Canada or should I send it to my relatives in Canada and ask them to mail it to IRCC, also as don't have any permanent address now, can I give my relatives address in the declaration form)
2. Apply for PRTD ( in case family has to go for Citizenship test, we applied for our citizenship before we left Canada)
3. Travel via US border ( Family does not us visit visa, and waiting time for appointment is approx. 1.5 years)
Sorry, lots of questions, but will be greatfull if you can advise.
Thank you.
