Argentina's current law treats immigration as a human right and consequently prioritizes the reunification of families, facilitates the ability of immigrants to obtain residency, and allows free access to health care and education. Immigrants are also granted a right to legal counsel.

It is also possible to look for a job once in Argentina on a tourist visa. Europeans can travel to Argentina without a visa and are automatically given a free 90-day tourist visa upon arrival. After finding a job immigrants can go to the migrations department with a letter from their employer and a certificate of good conduct from their country of origin.
