One year ago, when I applied for Study Permit and come to Canada I have all my personal documents notarized, including my birth certificates, my education diploma, etc. Now I am applying federal skilled worker and need to submit those documents again. I know for police clearance it has to be issued within 3 month prior to your submission, however, how about other documents, such as birth certificate? Do I need to ask my relatives in my home country to do all the paper work again, or I can submit what I used one year ago? Many thanks!!!
