We had quite a lot of foreign students on the course and they were all, without exception, completely awesome and great people to do a course with. Mind you, Norwegian moonshine is horrific...
Funnily enough, as a full-fee paying international student, I had an easier time learning in India than in the US a decade or so ago; the only thing that made my masters education worthwhile was the research opportunities, the general quality of students, and an easier job market (at that time). Given that all three are in decline right now, I would not advise anyone to pursue masters abroad.
[1] by well-regarded, I mean well-regarded by eg people at competently run well-paying firms who do hiring, rather than eg people who are really into politics and who have idiosyncratic opinions about particular universities
Part of my bias is that I was an exchange student at RIT and while I appreciated the experience, I was not impressed by the CS courses or the level of maths of the students going there.
