This paperback is part of the ACLU (American Civil Liberties Union) Handbook Series. Virtually all the protections written into the Constitution are stated in universal terms applicable to all persons, aliens as well as citizens. The disparate treatment given to aliens has come largely from legislative acts of federal and state governments during periods of hostility toward immigrants of differing racial and ethnic origin and against persons regarded as disloyal in times of war and ferment. The Supreme Court has continously held that Congress has the absolute power to exclude and to expel from the United States any aliens it chooses. Using a question-and-answer format, this book attempts to define the rights of aliens in the United States under existing laws. It will help aliens and those who assist them to know, to understand, to exercise those rights and to extend their opportunities to function as full members of the American community.
