Answer:
Economic opportunity
Step-by-step explanation:
Economic opportunity is generally thought to have been the main draw that drew immigrants to the United States, based on historical data and analysis. Due to the nation's quick industrialization and labor shortage, immigrants had many job options. The United States was also regarded as a land of opportunity, where perseverance and hard work could result in success and upward social mobility. Immigrants from impoverished areas found particular appeal in this promise of economic prosperity. Even though land abundance and freedom were also significant factors, economic opportunity frequently took precedence.
