eventually returned to their home countries
Explanation
Many new immigrants entered in the US in the late 1800 in large numbers and most of them were from western and northern Europe.

Others were moving to US to seek for freedom due to the political and religion persecution. Many immigrants eventually returned to their home countries this is because in their mind they didn't come for a permanent stay.
