I apply several colleges,can I use one of the offer given by the colleges to apply visa,and after going to Canada I can choose whatever college that gave me the offer to attend?
wrong group bro.
There is a student visa section, where you can post these types of question.
But, an answer to this question: Yes, you can change after you come to canada.
The point should not be described by a term"change",Suppose I haven't pay tuition fees to any colleges,I got study permit and know exactly my targeted college or use it as a mean to catch up my late application(i.e.:I am currently having my latest IELTS band 6 but my targeted school is red river college which demand IELTS band6.5,I am now applying the college in ontario which demand IELTS 6.0 and at the same time I am going to register IELTS test next month,and I will get the offer from ontario college and use it to apply Study Permit,Suppose I fulfill the IELTS score and get the result 1.5 month later and start to apply red river college.After I got study permit I will pay the tuition fees to red river college and formally get enrolled in red river college and refuse to enrol the ontario college which used for applying study permit),Is it ok this way?
