I haven't logged into this forum for over one year, but I'm back to just say that it is most probably NOT possible to acquire Argentine citizenship solely via investment. I will be waiting for Dr. Rubilar to comment on this proposal. In my view, what perhaps could be done is selling a residence permit, but there is NO way at ALL to acquire CITIZENSHIP (!!) by NATURALIZATION (!!) without living 2 continuous years in the country. Source: The National Constitution, Article 20; Law 346, article 2, section 1.
For anyone who thinks this would be like a Caribbean CBI, where you'll be getting a passport in 6 months without living in the country, think again. Citizenship here is a judicial procedure, not an administrative procedure, and according to the aforementioned law 346, you must manifest your will before the federal judge in the area in which you're living, ahem, who has full discretion over your case, as every court has a set of unique requirements (for example, some ask for cuit/cuil, others don't care).
Now, article 20 of the National Constitution has an exception to shorten the time to naturalize for people who "allege and prove services to the Republic," but quite frankly, I just can't see many, if any, judges agreeing that paying $500,000 is a service to the Republic.
I mean, I guess it's not surprising that a crypto scammer is trying to sell citizenship. I think he might have copied this one from Donald Drumpf with his "Golden Card" idea that never came to fruition. What a coincidence, they're both crypto scammers.
Anyway, I hope and am thinking that a judge will declare this proposal unconstitutional.
