How do i find demanded Major subject after 4 years of my education, I will get good Corporate Job?

I would add, since I don't see it here yet: strongly consider not spending 200k for an undergraduate degree. There is nothing wrong with doing a couple years at a community college and then a couple years at a big in state Uni for a total tuition cost of like 25k. Repayment on that is not nearly as difficult (interest on a 200k loan kills you).

These are very good questions that every student should be asking! Search online for careers in demand and also look at websites that list average salary data. This will give you a lot of information. From my personal experience I can tell you that the IT market remains strong. Fastest growing areas are in data related careers such as IT or data security, data scientists, database, etc. Good luck!

I recommend you look for subjects that you're passion about and you'll do well.  Once you do well you'll be able to find a job.  It's very hard to predict what's going to be in demand 4 years from now since things are constantly changing so fast.
