The America First Act is like a set of new rules that limits who can get help from the government in the United States, such as health care and housing, only to certain people who are allowed to be in the country. It also tries to make sure cities that protect immigrants follow these rules, and it even stops some organizations from using government money to help people who aren’t allowed to be in the country.

The America First Act wants to change who can get help from the government, like money for school or health care, depending on if they're allowed to live in the country. It tries to save money by giving less to some people and asks people to show more proof before getting help.
