If you want a good salary package in an MNC then go for MBA.

You shouldn't change your line as you are an engineer then you should prefer M.Tech and many colleges have their own criteria for admission process. I would suggest Indo Global Group of Colleges to prefer as this college is in Chandigarh and has good infrastructure as well as placement assistance.

You can very well go for MS from any foreign universities,US universities are best for MS. You need to crack GRE and TOFEL(English proficiency test). If you want to pursue M.Tech crack GATE and get into IITs/IISC. A good score in GATE will also open opportunities to get a job offer in PSUs.

It depends upon your interest. If you want to pursue your career in civil engineering go for M.Tech, if not come to MBA. All the best.

Dear Kishore,
It's up to your and skills, of course, you can get good salary packages after doing M.Tech & B.Tech dual degree courses. I would suggest you to choose CSE branch.
