What is the better major for better job opportunities and pay?

Is it B.S in Informatics or a Bachelors in Business administration with a concentration in Management information systems?

One thing that’s very good in IT is that people GENERALLY don’t look at your education and prefer you to have good hands-on skills instead. So do some research which major would provide you more of them. Another very important thing while in college is networking. See which major can offer more of it.

Since u can expect to work for 30+ years, why not pick the one u actually prefer to do.

If you like programming, do Informatics. If you like business, do the business one. I doubt one pays much better than the other.
