I am wondering about the immigrants who came to America in the 19th century?
I have been wondering a couple of things as of lately:
1) During the 19th century when billions of Europeans came to North America, did they have some kind of quota to “fill” as of how many immigrants that could enter the country?
2) Were all the immigrants allowed to travel freely in the country after Ellis Island?
3) When and how did the new immigrants receive citizenship?
