Hello Amit. I would like to tell you that yes a regular master degree is valid irrespective of the job or profession you are carrying on along with it. If you can manage both the things simultaneously, then there will be no issue in getting your degree. I would also like to mention that there are certain master degree programmes in India which are meant for working professionals only such as MBA (Executive) program. So, if you can manage both the things then you can definitely your master degree will be valid. I hope you found this answer helpful. Good luck.
