Dear Mr. Solanki,
If you are interested in completing a Ph.D. in Business you need to do the following:
First, you have to write GMAT and do extremely well. It can be written on-line from India, but I suggest you prepare thoroughly before writing the test.
Second, you will need excellent letters of recommendations. The people you choose to write reference letters should know what to write. They have to provide evidence for the content of their letter. One thing they have to write certainly is that your Second Division in your B.E. does not reflect your true ability and that you possess intellect, personality, inter-personal skills and leadership skills that are required for acceptance in a good Ph.D. programme.
Third, you will need to write a real good statement of purpose as to why you want to pursue Ph.D. and how it relates to your background and future plans. You can look at few university websites for the kind of things they want you to include in a personal statement.
If you make a concerted effort I think you can be successful. But at the same time I feel you have good chances of succeeding in getting immigration as an independent skilled worker to Canada. If you apply now it may take an year or more, but once you arrive as an immigrant you have lots of rights and entitlements to financial assistance for doing Ph.D.
I hope these comments are of help to you.
Good luck and keep in touch with me.
Birbal Singh
