In general terms, the factors that contributed to an immigrant's economic success or failure in a new location were the following.

Immigrants needed to learn the English language. Not all immigrants came from England or Ireland. They came from Italy, Germany, and other European nations. Years later, Asian people started to come to North America, basically from China and later from Japan. Many years later, Hispanic people who speak Spanish from México, Central America, and South America.

Then, another factor was that immigrants had to fit into the American culture. These immigrants had their own culture, traditions, history, and beliefs, so different than the American ones.

Then, their perseverance. They thrive against all odds. Immigrants have never been totally accepted in the United States. So the ones that thrived, was because they were perseverant and worked very hard night and day. And doing that, they made and have made a great economic contribution to the economy of the United States.
