ICFAI Business School (IBS), Gurgaon Eligibility

Yes, it is legally valid and you can choose different options regarding that.

Apart from Hyderabad, Dehradun & Jaipur campus IBS runs an autonomous institute which awards PGPM. Though, you still have an option of having MBA with PGPM with IBS, Dehradun as like what I did while pursuing PGPM from IBS, Gurgaon.

CPA, I believe is a Certified Public Accountant, is a professional course which is different from Chartered Accountant(CA) or Chartered Professional Accountant. As far as I am concerned, any professional course does not need any degree from any college(Being it a graduation or post-graduation). But do take an advice from an expert regarding the same. Apart from this, your post-graduation will not be affected by any professional course. In fact, it will add value to your work-experience. All you need to do is manage your time effectively and efficiently but I would suggest you to pursue one thing at a time.
