For example, I'm looking at the UK, and grad programs there tend to take one year to complete your degree.
Have you add in living expenses and shit, too
True enough. Researching it a bit, you can have a part time job while studying and some places help students with living areas. UK suggests 800 pounds per year if you're a student and Uni can cost 5-6k quid a year. Since grad school will only be a year, that's at least 6800 pounds for that year with maybe 1000 pound extra for utilities, food, internet;etc. With some saving, it's definitely possible.
I'm going for it once I get a good job over here so I can pay off loans.
In today's world of globalization, an international degree speaks volumes. I definitely think it'd be worth it. Not only would I have a master degree, I'd have an INTERNATIONAL degree. This would break necks. In a country where the BA has become the new High School diploma, it's just the perfect edge you need to step your game up.
