Hello Everyone,
Hope everyone is in great health!

This is Navtej from India.
I am a CS graduate with CGPA 8/10, and currently working as a Technology Consultant with one of the big4 firms.
I recently gave GMAT and scored 700(Q49 V36).
I really have no idea if this score is good or bad and currently, I am phased out on which college to apply for.
Some of my concerns:
-I will have 3 years of work-ex while entering the class, which is usually considered on the lower end of spectrum.
-With 700 and IEM(Indian, Engineer, and Male), I don't know which colleges should I consider applying to.
Within my work ex, I held leadership positions and also had a promotion.
I was also part of core board of various CSR activities at my college and my organization.
Other than that, I also hold Public Relations Manager and Treasury positions at various local community clubs.
Due to active involvement in out-of-my-field engaging activities, I became pretty much interested in Marketing side of things and want to get the right skills for the same.
I am looking to focus my time while MBA at Marketing and would love to find positions (Marketing Manager, Brand Management or Product manager) in CPG or Technology Industry in US primarily.
I also reached out to colleges such as Fisher, Terry, McKim, Madison, COX to see what I could make up of my time at MBA, and now I am more confused.

Would love help from anyone who can help clear out some air.
I know suggesting school or admissions may not be at anyone's hand, but would love to see any of the factors that might help me to make a better decision.
I tried to be as thorough as possible, but let me know if any more information is needed.

It sounds like you need to do more research than you will get from posting this. The US is, as you should know, one of the most challenging countries to get a visa. You are unlikely to find permanent work with an MBA from the school's you mention. 

Hey Duncan, Thanks a lot for your response. 
Just requesting your opinion for these colleges, do you think these will match with my post-mba goals?
And, the next question is, will my profile be competitive there?
Schools: Rice/Carlson/WPCarey/Fisher/Simon ? (These are ones I am considering to apply)

Schools that I think are totaly out-of-reach: Tepper/Kenan-Flagler/McDonough/Foster/Kelley.

I know this would be a lot to ask! But any help would be appreciated.

Take a look at the GMAT Teirs post, linked on my profile page. It's just very unlikely that you will get a visa past the OPT period. 

With just three years of work experience, it will be challenging to get into your target schools. As you are part of a very competitive applicant group - and your work experience is somewhat of a handicap - you might want to work on your GMAT score, getting the verbal score up nearer to your quant. This would help you a bit, but you probably also want to apply to at least one less competitive 'safety' school. 

Long-term, yes, Duncan is right in noting that the US is a risky bet, with the H1B lottery.
