I have logged file in feb. and got reviewed on 12 march but did not get Aip or study permit applied in alpha college
Are you aware that Alpha College is a private school? Private schools have a very bad reputation in Canada. You will also not qualify for a post graduate work permit once you complete your studies. Completing this program will not help you to get PR in Canada in any way.
This is a really bad option for studying in Canada. It's a complete waste of money.
If you want to study in Canada, you should attend a public college or university. Stay away from all private schools.
