Start a startup while graduating ,possible ?

hello , i am a guy at his 22 , graduating in engineering final year in india, i always wanted to start a startup but the problem here in india is that i cant find seed investment(not great startup culture) , so i decided to come to usa for MS(master of science), now i have following questions :

1) can i start a startup while graduating in usa having a american co founder and joining after an year ?

2) if its possible ,how much difference does reputation of college makes (i do not intend to to take a job) on finding future co founder ?

3) if thats not possible then what are my possible options?

p.s. i asked this before but couldnt get any satisfactory answer.

your advice would be critical in my carrier decision thanks
