thank you for answer. sorry for confusion I made. I don't have two citizenship yet. Only one: ukrainian. and I live in Canada now and applying for PR.Quite tricky bcz u have 2 country citizenship. But national identity would be the identity card of the country were you currently live with citizenship. To make is more easy would suggest to give identity details from the country u applying or already applied.
before for different visas and permits ( study permit and visa) and for travelling out and back to Canada I was using my international ukrainian passport. for different documents and staff in Ukraine I used to use my local ukrainian passport, do they need in CIC number and translation of it??
