The Naturalization Act increased the Residency requirement for American citizenship from five to fourteen years, required aliens to declare their intent to acquire citizenship five years before it could be granted, and rendered people from enemy nations ineligible for naturalization. The subsequent Sedition Act banned the publishing of scandalous or malicious writings against the government. The acts were designed by Federalists to limit the power of the opposition Republican Party, but enforcement ended after Thomas Jefferson was elected president in 1800. Have A good Day. </span>
