Milei is introducing a presidential decree to reform immigration law without having to go through congress which is illegal.
Now applying for citizenship is 100x harder (requires proof of income which a lot of people don't have) and non residents can't get free healthcare and education.
I came here with my parents in the 1990s and we never bothered to get citizenship because you already get all the advantages by being a resident or temporary resident.
Now my parents won't be able to get healthcare.
