Hi
Dear Usman,
If your uncle is going to sponsor you then he has to initiate the process first, he has to fill the forms that will be sent to you first for signature and submitted to Mississauga Office and once it will be cleared from there then the process will start at Islamabad High Commission...
Please take some time go through the
www.cic.gc.ca over here you will find the complete information about the whole process..
If you do a little Google search for top universities in Canada you will find your answer regarding where to study.
Thank you and best of luck...
You can't be sponsored by an Uncle, he can get 5 additional points for a relative in Canada. He would need his birth certificate, his uncles birth certificate, and depending on whether it is mothers or fathers brother that persons bc. He would also require proof that the Uncle is legally residing in Canada.
