how can I apply for my study permit as Bosnian citizen and include my child U.S. citizen on it

[Emina]

Hello,

I am bit confused. Now I received acceptance letter from one of Canadian Universities Vancouver and as I am single mother and my parents are pass away I want to take my child with me considering that she dont have nobody to stay with.

Now I am Bosnian citizen and please advise do I apply for TRV or study permit first or how that goes? I have been reading somewhere that I first apply for TRV and then on the Board I get Study permit??Also do I need ETA? Please advise.

Also since my child has dual citizenship and she is U.S. passport holder and I want her to accompany me please advise do I need only to check her in on my application and complete family information form or do I need separate application for her, does she need TRV or ETA or anything considering that she is U.S. passport holder.

Also if approved please advise how I should renew her staying considering that she is U.S. citizen and I am not?

I also have sponsor for my and her staying in Canada while I am study and living there so please advise what proof I need to provide on my application. Sponsor is U.S. citizen
