I wanna go and do my master, but the fact that i might not get a job/visa after investing so much is deterring me. I have years experience in R&D is a very good company. But wanna get into good r&d projects (like the IBM watson project) but its difficult here in India. am really confused. By the time i go for MS i would already have 4 yrs experience and not sure if MS by research is a good option then. ANd you just said its quite tuff. Very tuff means “very tuff” ? :( considering the time and money investment am gonna make.
