Hi
I hope someone can help.
I have partly found the answers in other threads, but not all of them, so I'll add them here as well.
Background:
My wife is Canadian citizen (I am a European citizen), but also hold citizenship in another country, where we both live.
She was naturalized with her parents, at the age of two, when they immigrated to Canada, but they left to her present country when she was six.
She has two children from a former marriage, who both are citizens in the country of residence. Both children are born before 2009.
The questions are:
1 - Are her two children considered Canadian citizens?
2 - Does it make a difference for them, if she apply for them when they are minors, or if they apply for themselves after the age of 18?
3 - Is it correct that they will have to take a language and knowledge test, from the age of 14, as well as express intent to live in Canada?
Thanks in advance.
