Ya, you dont need to learn the native language esp in Norway, Sweden and Denmark,(almost everyone speaks fluent English) ofcourse its a plus, if u know it, if u have some extra time, enroll in a language school for immigrants for a yr, its free anyways. And yes, u have higher chance of getting a job in international companies if ur studying IT, I heard that there are some nepalese working in Ericsson, ikea, nokia, tetra pak. But its difficult to support yrself as a student but its same in every western countries, here atleast u dont have to worry about payin for ur tuition.
