Request you to please contact the college officials for the same.

You will be called for admission after verifying your documents. There will be an interview thereafter.

Hi Vatsal, can't say if its good or bad but its a highly publicized university. You can keep it as a last option as there are better universities too.

Hello Akshay,
It's very nice to see your dream of studying abroad. Yes it's unique experience. I would advise you to contact an agency in India dealing with admissions in US universities. There are many nuances and if you miss even one, chances of admission diminish.
Best wishes
