Thanks for your reply. It was very helpful. I have the following reasons.
Your age is older than the typical U.S. MBA program by three years
I was struggling with immigration and green card for so long. If you are not aware, changing my status to students visa (non-immigrant visa) after filing for immigrant visa would show conflict and will pose problems. Because my employer started filing for my green card in 2004, I was not able to switch between non-immigrant and immigrant status. Is this a good reason ?
your community/extracurricular is not stellar
I forgot to mention that I used to play in the semi-professional Cricket league for about 18 months and later conducted a quadrangular cricket tournament and participated in it. Will this suffice for community/extracurricular ?
I am planning to get my application into Columbia for 2008 ED. Columbia is my first choice school. Do you think this will increase my chances with a GMAT (scheduled nex week) between 650 - 700?
Please let me know. Thanks again.
