Retirees can apply for either a retiree visa or a steady-income visa.
For the retiree visa, you must proof your retiree status as well as of a monthly pension.
The steady-income visa requires you to show proof of a minimum monthly income.
The number for the steady-income visa changes but it is usually around US$2,000.
Other visas available include university student visas and work visas, the latter of which requires a local employer to sponsor you.
The financier (or rentista) visa is the most flexible of the visa options. All it requires is a guaranteed minimum of whatever type of income, and that it can be transferred to an Argentine bank.
Argentina has a minimum residency requirement that individuals must meet in order to maintain temporary residency.
First, once temporary residency has been renewed twice (so someone has been temporarily residing in Argentina for three years), that individual can apply for permanent residency.
After two years as a permanent resident, you are eligible to apply for citizenship.
Most, importantly, you must physically be in Argentina for the majority of that time.
In short, residency in Argentina can lead to a second passport and dual citizenship in this country.
