Hello, folks! 
I searched on the internet and peoples say the Student Permit and the Visa for we, international student, to get to Canada are different. Thus, I am wondering about these two application:
Application to Change Conditions, Extend my Stay or Remain in Canada as a Visitor or Temporary Resident Permit Holder
(the application that I found at Application to Change Conditions or Extend Your Stay in Canada as a Visitor. Is this application potential to extend my visa?
)
Application to Change Conditions, Extend my Stay or Remain in Canada as a Student
(the application that I found at the extend student permit's part :'()
Please! Please help! I am so confused, now ??? ??? ???
