Modifications Parts of the Act remain in place today, but it has been amended many times and was modified substantially by the Immigration and Nationality Services Act of 1965. When regulations issued under the authority of the Passport Act of 1926 were challenged in Haig v. Agee, Congress enacted § 707(b) of the Foreign Relations Authorization Act, Fiscal Year 1979 (), amending § 215 of the Immigration and Nationality Act making it unlawful to travel abroad without a passport. Until that legislation, under the Travel Control Act of 1918, the president had the authority to require passports for foreign travel only in time of war. Some provisions that excluded certain classes of immigrants based on their political beliefs were revoked by the Immigration Act of 1990; however, members of Communist Parties are still banned from becoming citizens of the United States. After the September 11, 2001 attacks, President George W. Bush implemented the National Security Entry-Exit Registration System and other border and immigration controls. In January 2017, President Donald Trump's Executive Order 13769 made reference to the "Immigration and Nationality Act".
