Giery86, I don't mean to jump on you at all, but if you get most of your information regarding what you mention related to poor MERCOSUR citizens residing here from your girlfriend - a word of caution. Many Argentinos are quite prejudiced against poor people from other MERCOSUR countries. Take what she tells you with a grain of salt until you meet some of these immigrants yourself and get to know them.
My wife is Paraguayan, moved here about 7 years ago. Since she and I married, we have brought about half of her immediate family here (6 here - another 6 back home) and many cousins, aunts and uncles, from Paraguay because as screwed up as things are here, there are better (all relative) opportunities here than there for the very poor. I know MANY of these poor immigrants through meeting their friends, and family of friends, in all walks of life here. Only two of all we've brought over I've found to be worthless, and those returned to their poor-prison in Paraguay. The rest are honest, hard-working people.
During our life here together, I've seen many cases of plain, open prejudice directed against them, and many cases that were questionable - i.e., reasons giving for denying them something didn't really make any sense.
As in the States with Mexicans and other poor immigrants (legal or illegal), poor MERCOSUR residents here work their a**es off to make a better life for themselves and send money home to their families. Are there drug dealers and thieves amongst them? Absolutely!
But look beyond the "conventional wisdom" here and understand a little more about what goes on. Believe me, there are plenty of Argentine thieves, drug dealers and other criminals. Plenty. And the laws, the lack of good police protection/prevention and of a fair and equitable justice system make their lives pretty damned easy.
There are TONS of good, hard-working LEGAL immigrants/residents from other MERCOSUR countries contributing to the country as a whole, even though many Argentinos, who don't want to admit that they have a lot of aboriginal blood running through their veins, don't want to admit it.
BTW - I should correct some of my statements - when I mention Argentina here, I really mean Buenos Aires. I'm not qualified to comment on anything outside of the city of Buenos Aires and to the north in the suburbs, between the two where I've lived for 6 years.
And I agree with Camberiu to a certain extent related to immigrations policy here. It is as well about the only thing with which I fairly strongly agree with the government on. Also, the government being a part fo the MERCOSUR, they don't have any choice - that's a MERCOSUR privilege.
Here I am, a citizen of a country that was built on immigrants, and I can't bring my wife to the States for a visit on a tourist visa. I have to spend a lot of money and time to get her a spouse immigrant visa just so my wife can see the country her husband comes from. I don't live in the States any more (I am still a citizen - the only time I'll renounce my citizenship is when Texas secedes
) and I don't want to go through all of that hassle just so my parents can meet their daughter-in-law (they've never met her - they are getting old and frail and my father is going through cancer treatments).
Why won't they let her in just to visit? Because she's from a poor MERCOSUR country, isn't rich herself, immigrated to Argentina and even though married to an American they told her that they fear she might continue her immigration pattern to the US and stay there illegally. Even though she did EVERYTHING 100% legal here to gain her permanent residency and live and contribute here.
How freaking stupid! WHY would she stay illegally in the States if we were going to move there, when I can get her into the country as an immigrant legally??? The US makes less and less sense every day, at least to me.
If Argentina would follow its own laws a little better, they wouldn't have such a crime problem to begin with. If they opened their economy to allow it to perform the way it could, there would be a lot less crime as well because there would be fewer poor people thinking they have a right to take stuff from others - because they would understand better what owning something means and would have opportunities too boot.
MOST Argentinos (just like in the States) would not work where the majority of the poor MERCOSUR immigrants work - what do they do when they feel like they don't have opportunities at the level they think they should be?
In the meantime, in my opinion, Argentina is way ahead of the US in terms of immigration policy. And as many people on the forum could probably tell you, I'm a critic of Argentina in many things, but not this.
