Answer:
Immigrants knew that Americans held no prejudice against foreigners
Step-by-step explanation:
From the available options, the statement which was not a reason for the huge migration of people from their homelands to the United States in the mid-1800s is "Immigrants knew that Americans held no prejudice against foreigners"
