My nephew who just completed Higher secondary school in India and now is planning to come to canada for the diploma/adv diploma courses one of those accredited colleges in Ontario.

1. what is the process for applying for the colleges. What do they need?
2. What is required (those undocumented things) for the student visa? any tips?
3. Would it help for the visa/admission process if I become some sort of financial gurentor for him?
4. we are mainly interested in one of those Technical courses at Centennial / George Brown / Sheridan (within GTA). How difficult is it to get the admission/acceptence?

Are we already too late for the Fall session (in terms of admission and student visa process) or we can still apply?

Any help in this regard would be greatly appreciated.

Thanks in advance,
Mehul.
