Just join a company and gain practical experience......and later u can pursue ur studies....No Cmpny Wants a highly qualified person at higher ranks but a highly experienced....Think If U own a cmnpny....do u hire a highly qualified with no experience person as a senior engg...?

after btech u could join in M.s in usa on your interest and also join in m.b.a and m.tech othere wise write exams and search for jobs

You can go for Masters in USA jn embedded systems where high paying jobs are abundant. you can also go for Mba in Marketing where you can apply technical knowledge in technical core companies.

you have too options either go for MBA or mtech ..if u want to make carrier in design or r&d go for mtech ..other wise you can join MBA
