Why do u think more immigrants have settled in coastal states than in landlocked states?

Immigrants nowadays are more widespread, but when America was experiencing major waves of immigration in the 19th century, immigrants did tend to settle on the coast. Immigrants came on ships back then, and the two major facilities for accepting these ships and processing the immigrants were in New York City and San Fransisco. Both of these cities are on the coast. We have to remember that immigration was much more difficult back then, with many people having to flee their countries without any of their possessions. This means that they had to restart their lives when they arrived in America. They clearly didn't have enough money to travel very far from where they arrived in America, so they tended to have to stay in either San Fransisco or New York. Immigrants built families and communities there, leaving these coastal states with rich diversity and history.
