The Act has five chapters to it, each having provisions to what the process was to gain citizenship and to not lose it. Chapter one of the act outlines the definition of terms used in the Act. Chapters two and three are the largest parts of the Act and they deal with identifying eligibility for citizenship and specific residency requirements for people born abroad to one U.S. citizen parent, or non-citizens born in the U.S. or its territories. The third chapter of the act goes into detail about nationality through
naturalization, giving a further clarification of requirements for non-citizens seeking naturalization. It goes into detail with specifications concerning race, ethnicity, and basic verbal English proficiency along with residency requirements outlined. The fourth chapter is about loss of nationality. Exceptions to residency requirements and removal of citizenship are made for those away in the employment of and under orders from the U.S. government or for other specific reasons, and loss of nationality by actions of children under the age of eighteen is prevented except when such a person is convicted of treason or fighting against or trying to overthrow the United States. Apart from such exceptions in the fourth part of the act there are many possible ways to lose citizenship by those who had gained it, many of which refer to the idea of not showing consistency with being a citizen either by leaving the country for periods of time or by taking up government positions in foreign states. This chapter of the Act also dictates that its provisions shall not override any existing treaty or convention to which the United States was a party. The fifth and final chapter of the document deals with the miscellaneous, including the procedure for determination and notification of loss of nationality and a list of previous Acts and parts thereof to be repealed and superseded. The 4th and 5th chapters were indirect tie-ins with the Alien Registration Act of 1940, also known as the
Smith Act. The Smith Act, enacted June 29, 1940, set criminal penalties for advocating the overthrow of the U.S. government along with requiring all non-citizen adult residents to register with the government. The Nationality Act of 1940 would take it a step further and make it so that anyone suspected of advocating the overthrow of the U.S. government who had recently gained citizenship would lose that citizenship and face criminal penalties. ==Related laws==
