- High unemployment in Italy, lack of job opportunities, especially in southern Italy
- Lower wages in Italy compared to the US, especially for unskilled labor
- Large scale industrialization creating surplus labor in rural areas
- America's booming economy and rising industries, like steel, textiles, meatpacking offered better job prospects and higher salaries.
Political and Religious Freedom
- Political instability and corruption in Italy
- Oppressive regimes, lack of democracy and civil rights
- Religious persecution, especially of Protestants and Jews

Family Reunification and Social Networks
- Many Italian immigrants already had relatives or friends in the US who had migrated earlier.
- Chain migration, where established immigrants sponsored the passage of their family members and fellow villagers.
- Letters and remittances sent by earlier migrants encouraged others to follow.
Steamship Travel and Immigration Policies
- Advancements in steamship technology made transatlantic travel faster, safer and more affordable, lowering the cost of immigration.
- Relatively lax immigration policies and laws in the US, until stricter quotas were introduced in the early 20th century.
