So probably you don’t know, but it’s more or less the same in The Netherlands and Italy. If someone illegal gets a child, the child does not automatically obtain citizenship.
In Italy there are rules like children have to continuously live in Italy for 18 years to obtain a Italian passport, in The Netherlands there are certain procedures but it definitely isn’t easy. And every now and then you’ll hear a genuine sad case, but overal being born somewhere doesn’t equal getting that passport in many countries. Apparently it’s the opposite in the US? So being born there, even with illegal parents, gives you the right to get a US passport?
