Please help me to find my eligibility for Business Schools in US

Hello,

Please help me with below question. I have approached couple people but did not get concrete answer.

I finished my 10th standard in the year of 2000. From 2000 to 2003 I did my FULL-TIME Diploma in Electronics and Computer Science. As soon as I finished Diploma in 2003 I was recruited by a IT firm as a Network Engineer. So I started working FULL-TIME after my diploma. Till now I have 6 years of FULL-TIME professional experience. During these 6 years I did Graduation (B.Tech.) in Computer Science from JNT University, Hyderabad. This is a 4 years correspondence graduation course; we have to attend 1 month classes per years and exams will be condicted once in a year. I finished Graduation (B.Tech.) in January 2009.

Now my question is am I eligible for applying MBA in US top business schools (Harvard, Warton, Stanford, Kellogg and Chicago GSB)? If I am eligible how should I justify my correspondence graduation? I am planning to take GMAT on December 2009. Please help me in this regard.

Srinivas.
