Having been doing business in Argentina the last 6 years, specifically in the software development field, I'd say it's not a great place to start a career in the field, at least not as a foreigner.
6 years ago the development industry here was booming. There were a good number of well-trained developers available. Foreign companies were coming in here like crazy (I was one of them) to take advantage of the half-way decent infrastructure and education, mixed with low prices compared to the States and Europe related to development.
Around 5 years ago it was getting more difficult to find programmers at a cheaper rate. The market was "bubbling" as developers began hopping from company to company, in order to raise their salaries as developers became scarce. As happens in bubbles, companies started paying more to keep people from jumping, but that doesn't really help in the long run The development companies here had some room to move in that as they were paying their developers relatively small (to what they were charging the foreign companies) salaries and had a relatively high profit margin. But those companies were feeling the squeeze and prices to the foreign companies began to raise, Not enough to make it unprofitable, but enough to create a squeeze.
Then everything began falling to crap economically globally. That hurt the industry here, starting in about 2009 or so. Combined with rising salaries for workers and foreign companies slowing down because of the world-wide recession, many of the developers I knew began looking for jobs outside the development companies here when they could.
Now, in the last year or two, with Argentina becoming more and more expensive, the government acting the way it is, etc, more projects have gone elsewhere.
Many foreign companies are finding other places. And it's not just the money, it's also some of the things that are inherent in the culture here - things like people not showing up to work at random, showing up late, lack of a good work ethic for the most part. It's easier to tolerate issues like that when things are cheap. The higher the prices go, the less one can tolerate the inefficiencies that arise here.
I'm not saying there isn't a market here, still - there is. It just isn't what it was 5-7 years ago and getting worse, as is about everything else here economically. I don't things things have actually declined, but the growth has certainly declined. As we have seen in other places, particularly the States in the early 2000's, bubbles tend to burst, even in the IT field. With the direction the government is taking on many things I wouldn't count on the industry growing much more, not too soon, and would count on it shrinking like everything else here. The industry here pretty much depends on the international market - there's not a whole lot of local development needs here that I'm aware of. Slow economic growth internationally isn't going to help things here.
Most of the guys I know now are working telecommuting jobs directly for US companies now. Those are the higher-level developers. I don't really know what happened to the junior guys, I assume they are still continuing on in lower-paying, probably local, jobs.
I have been a bit out of direct touch with the development houses here for a couple of years. Maybe there's something I don't know, but the last thing I would depend on is an article from La Nacion telling us that future prospects are bright here for developers.
Directly to the OP related to moving here - think real hard about this. You will not be able to work for anyone here (in the kind of job you will be seeking) until you have some sort of work visa. I'd be very surprised if there weren't pretty much enough developers here, despite what the La Nacion article says. They mention a need for 7000 new developers a year to handle the demand - that's not really very many people in a growing industry, and those projections are usually based on rosy pictures of straight-line or asymptotic curves that rarely bear any relation to the reality that comes in the future.
I think most companies here are going to hire Argentinos before foreigners, and to get in here and get a job quickly, I think you will need a company to sponsor you. You may be able to find that, but 6 months seems like an awful short time to do so, particularly considering that you don't know Spanish yet. also considering that, as near as I can tell, you have no experience yet.
If you're a quick study you might be moderately conversational in 6 months, I'd think - but I don't know if that's going to cut it. There are a lot of people who speak English here, to varying degrees, particularly in "educated" fields (i.e., a university degree), but I don't know if a company is going to feel comfortable about a programmer who is sitting in meetings and missing half of the content because he's struggling with the more technical aspects of the language. Someone who is merely conversational in Spanish is still missing words in normal conversations and having misunderstandings. I consider myself nearly fluent (my local friends tell me I speak excellent Spanish, but I know what I'm missing), and I live on a daily basis speaking nothing but Spanish except when I talk to a client or a local expat friend. I came here 6 years ago, not quite even conversational in Spanish (having had two years of Spanish in high school some 30 years ago and working in construction in my early twenties, alongside Mexican laborers) and I have a hard time with technical discussions sometimes.
And not to be rude or condescending, or what-have-you, but it's been my experience after a bit more than 20 years in the industry, that almost no one who comes out of any university is ready to sit down and start developing and be productive. There are exceptions, and most of these exceptions are.guys who have been programming nearly since they could read because it's in their blood. Their university degree was a means to an end - to get a job in a field that they are extremely passionate about. I don't know where you stand in the regard, so take that into account when you are thinking that you can convince a local company to sponsor you for a visa, if you have no practical industry experience and don't speak the language fluently.
I really don't want to be pessimistic, and I'll never say you can't do it - but think real hard about it. If you have plenty of money and can afford to come here and live for an extended period of time (I'd say plan for a year at least before you may find a good paying job, maybe longer), then that's a different story. But if you're on a tight budget and don't know much about the culture and the conditions here and are dependent on finding a good job quickly, you may find yourself in worse shape than if you stayed where you are, found a job to start gaining experience and perhaps start learning Spanish in the meantime.
I'd hate to see you end up working some crappy job for a low salary and living in a hovel, wishing you hadn't made the move.
