Expatriate Terrorist Act This bill amends the Immigration and Nationality Act to include among the grounds for loss of U.S. nationality by a native-born or naturalized citizen: taking an oath or making a declaration of allegiance to a foreign terrorist organization after attaining the age of 18; entering, or serving in, a foreign terrorist organization; becoming a member of or providing training or material assistance to a foreign terrorist organization; and accepting, serving in, or performing the duties of any office, post, or employment under the government of a foreign state, a political subdivision, or a foreign terrorist organization if the person knowingly has or acquires the nationality of that foreign state, or an oath, affirmation, or declaration of allegiance to the foreign state, political subdivision, or designated foreign terrorist organization is required for the office, post, or employment. The Passport Act of 1926 is amended to: prohibit the Department of State from issuing a passport or passport card to an individual who is a member, or attempting to become a member, of a foreign terrorist organization; and direct the State Department to revoke a passport or passport card previously issued to any such individual. A person who is denied issuance of a passport or passport card or whose passport or passport card is revoked or otherwise restricted may request a due process hearing not later than 60 days after receiving notice of the nonissuance, revocation, or restriction.
