Frequently Asked Questions (FAQ)
Under Section 1 of the 14th Amendment (the Citizenship Clause), persons born in the United States and subject to U.S. jurisdiction are generally U.S. citizens at birth, including children whose parents are unlawfully or temporarily present. The Citizenship Clause has longstanding exceptions, including children of accredited foreign diplomatic personnel with diplomatic immunity.
Federal jury service is an obligation of qualified citizens when summoned under 28 U.S.C. § 1861. Federal qualification requirements are principally set out in 28 U.S.C. § 1865 and include U.S. citizenship, age 18 or older, at least one year of residence in the federal judicial district, sufficient English proficiency, and absence of specified disqualifying conditions. Non-citizens are not qualified for federal jury service. State jury-service rules are governed by state law and may differ.
Under the Military Selective Service Act (50 U.S.C. § 3802), almost all male U.S. citizens and male immigrants residing in the United States must register with the Selective Service System between ages 18 and 25, subject to statutory and regulatory exceptions. This generally includes lawful permanent residents, refugees, asylees, parolees, and undocumented immigrants. Lawful nonimmigrants maintaining valid nonimmigrant status (H-1B, F-1, L-1) are generally exempt while they remain in that status.
U.S. citizens and U.S. resident aliens are generally subject to U.S. federal income tax on worldwide income under Title 26 of the U.S. Code. Resident-alien status generally arises under the green card test or the Substantial Presence Test, subject to statutory exceptions and applicable tax treaties. However, whether an individual is required to file an annual income-tax return depends on applicable gross-income, self-employment, age, filing-status, and other statutory thresholds.
Legal obligations commonly associated with civic life include complying with applicable tax laws, serving on a jury when legally summoned and qualified, and registering with Selective Service when legally required. Voting in U.S. elections is generally a legal right and civic responsibility rather than a federally mandated duty for ordinary voters, while staying informed and community volunteering are voluntary civic activities.
Generally, non-citizens may not vote in elections for federal offices. 18 U.S.C. § 611 prohibits an alien from voting in an election held in whole or in part to elect a candidate for President, Vice President, presidential elector, U.S. Senator, U.S. Representative, Delegate, or Resident Commissioner, subject to limited statutory exceptions. Unlawful voting carries serious immigration consequences, including potential inadmissibility or deportability under applicable immigration laws.
