Visa processing time

[Uma Rajasekaran]

Hello there,

I'm planning to apply PhD in Canadian universities. I have some queries regrading visa processing time.

• How long will it take to process visa?
• Should I need to be admitted in the college before applying for visa?
• If I want to join in college by next Summer when should I start the visa processing?

I'm in dark about the visa processing, deadlines, and admission processes please help me.
Thank you in advance.
