How much money did immigrant had to have in order to enter the US?

Historically, the requirements for immigrants entering the U.S. varied significantly depending on the time period and Immigration laws in place. For instance, during the early 20th century, immigrants were often required to have a minimum amount of money, typically around $25, to demonstrate their ability to support themselves. However, these financial requirements have changed over the years and are often influenced by specific visa categories and individual circumstances rather than a set amount for all immigrants.
