I do nothink its much good to do masters for engineering grads in India, so would suggest abroad for it.
People doing M.Tech in India are who wanna takeup job which they did not got as maybe because there college do not provide campus placement.
But much before,which college you are doing BE from.
And if you wanna do MS from abroad, you need to know you have to prepare for GRE, start doing it. How you do that, you start first with your summer internship which you do here in India or in any foreign universities.
Secondly remember, you have to bear the inital expense to go to do summber interns rest the Uni will give you enough stipend to cover your expense there and which eventually will also cover the inital expense you took on.
Inital expense I mean flight visa and all formailities and transportation.
