I am going to do my masters in computer science from abroad..But I don't know whether it will work or not to getting a high payment job

if you are under graduate computer science student you should not do Masters in computer science . this will be a conversion programs for non it students to do it. you have to do masters in any one of the specialised stream like networking,data mining ,multimedia like that. Because of specialisation
