What was the first test immigrants had to pass called?

The first test that immigrants had to pass in the United States was called the "literacy test," which aimed to assess their ability to read and write in English. Introduced in the early 20th century, these tests were often used to restrict Immigration from certain countries. The tests were part of broader immigration laws, including the Immigration Act of 1917, which sought to control the influx of immigrants based on perceived social and economic criteria.
