I want to do MS in civil engineering in US. Will I be able to get job opportunities in US after it or should I change my stream to CSE?

Hi, Changing your stream will make a very little difference as it is very competitive. Whatever you study, you must perform well in your class and be outstanding. Opportunities are there, but not easy to get. Find a good university, it is very important.

Yes, you can pursue MS in civil engineering. It has a good scope. You should opt for MS in structural engineering or construction engineering and management.
