If only it was as simple as making an "investment" of $500.000 to $1,000,000.
According to the article you linked to in your last post (errors in English thanks to Google translate):
"The City wants to become a regional center EB-5 visa for attracting investment for projects in the fields of construction, entertainment, tourism, education and health, said Mikki Canton, a lawyer hired by the municipality to analyze economic development projects.
With the appointment of Citizenship and Immigration Services (USCIS), the City could attract investment of $ 500,000 to $ 1 million for projects in certain sectors poor Miami. For entrepreneurs behind the projects, the EB-5 investments are a good alternative to traditional financing from banks that have been more difficult to achieve during the economic crisis.
Meanwhile, foreign investors receive conditional visas for themselves and their immediate family. Visas become permanent residence if you can verify that the project has generated at least 10 jobs for every investment."
Furthermore: "For its part, the City expects to charge an administrative fee to each investor who chooses to Miami."
If I had investments that I felt were at risk in Argentina, I doubt I would feel more secure about investing in a "project" in a "poor sector" of Miami that must "succeed and generate 10 jobs for every investment" in oder for me to be able to live in the United States.
If Sergio's. friend would have that kind of money to invest after selling his properties here, I hope he doesn't get involved with something like this just to get a visa hoping it leads to permanent residency. If investing in private property was all that was required to get a visa to live in the USA it would be worth considering, but the US is not going to start giving visas to foreign owners of pivate property anytime soon.
Perhaps they should change the inscription on The Statue of Liberty from, "Give me your poor, your tired, your huddled masses yearning to breathe free" to "Just give me your money."
