回複:**加拿大移民,新生兒體檢表急問**
I think you have to submit your son's application first, which requires your son's passport number and passport copy. It is very easy to apply a USA passport. Some post offices have this service. The application fee for kids is around $120.
After this, Canada Immi office will send exam form for your son.
I did have same situation as you.
Good luck!
