Question

What caused anti-immigrant sentiment to increase in the United States during the 1800s?

Answer 1

The fact that the America was largely increased by farming in the 19th century

Answer 2

It was largely caused by an increase in farming efficiency due to technology. Advancements led to a surplus of labor, and the displaced workers saw the United States as a place that offered them new opportunities. Many immigrants faced a double culture shock, not only assimilating into an entirely new country but in many cases switching from agrarian jobs to urban work at the same time.
