Everything In-detail about joining a University in USA particularly for Indians

Everything In-detail about joining a University in USA particularly for Indians such as more about EC's, the actual criteria what colleges want and all such kind of information that is really necessary for us. I'm requesting this because it took me so much research to do and a tough time in gathering information about this. Even though there's a lot while binging through YouTube,  Khan Academy being popular makes it a  very usable resource and easy to use. Also some information of how to manage  time for students with 9 to 5 classes and prepare for the college application. Not only this but also about the time to apply (such as early action, etc.) . Hopefully you look into this matter, Khan Academy is already perfect ! But please try adding this it would be very useful.
