I work in the film industry. Got my undergrad at Colombia in History, came here, spent two or three years studying acting/teaching English/being young and then studied film down here. I highly recommend the film schools down here, there are also many good professionals who give private classes. You will learn to film with no resources and solve problems, if you choose to go back to the US you will be able to produce with 10% of what they use up there.
Remember, film is a profession that does not value degrees much, in fact, you can study at a school like the FUC without taking your HS equivilancy, they will give you an "unofficial" dimploma that means nothing legally, but you can hang on your wall, and no employer will care. You can also study at the UBA, it will take about 7 years, it is free but you need your HS equivilancy.
As film is such a hard profession to break into, I suggest getting a degree in something else, something you like, maybe related to film, but something more solid so you can have a plan B. Also, in addition to film school you need to become an EXPERT at one thing. Something technical, like color correction, special effects, film accounting, sound recording, etc so you are employable. Film school can give you a very general education but to make money you need to be an expert in something (this applys to the US and here). It is a long road to be a director, and most people do not direct professionally, so you need to be able to support yourself. Plan on taking additional classes or doing an internship (unpaid) to get this skill.
I have directed two films but I don´t live off of that, it is my technical skills as an editor and also having a production company that keeps food on the table.
Your plan to get jobs in the film industry to support yourself is not realistic. There are 14000 film school students in Buenos Aires, in the entire industry there are maybe 1000-3000 jobs per year (and most are jobs for only the duration of the film, 4-6 weeks). There are 400 production companies in Buenos Aires, 90% have NO employees, meaning they are one person operations who hire free-lancers on a per-job basis. Estimate 1-3 years working for FREE to break into the film industry, to get your first paying job. Estimate 3-7 years to be able to live off of it (there are exceptions, some people get lucky or have an amazing skill. Note that I didn´t say talent, talent doesn´t count, but being the best chroma corrector does. Sound people always get jobs).
I love the film industry in Argentina, without the support of people here I would have never become a director. It is much nicer than working in Hollywood, there are some jerks but you can avoid them.
Also, there are many jobs in TV that could be had and other industries (filming parties, web videos, etc)
