In the years following the end of the Civil War which best describes the role of the U.S. government regarding immigration?

In the years following the end of the Civil War, the U.S. government adopted a more open and welcoming stance toward Immigration, largely due to the need for labor to support industrial growth and economic expansion. Policies encouraged the influx of immigrants, particularly from Europe and Asia, to fill labor shortages. However, this era also saw the beginnings of restrictions, as nativist sentiments emerged, leading to the implementation of laws that targeted specific groups. Overall, the government played a dual role of promoting immigration for economic reasons while simultaneously grappling with social tensions surrounding it.
