US citizens living abroad retain all rights and responsibilities of citizenship, including the obligation to file US tax returns on worldwide income regardless of residence (IRS, 2025). The US State Department (state.gov) maintains that citizenship can only be lost through specific voluntary acts, including formal renunciation before a consular officer abroad, and never automatically through long-term residence overseas. American expatriates remain entitled to consular services, US passport renewal, and federal voting rights under the Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA). Legal planning for US citizens abroad spans multiple jurisdictions and requires coordination between US federal law, state law of last domicile, and the host country's civil or common law system. The Federal Voting Assistance Program (FVAP.gov) administers absentee voting through the Federal Post Card Application (FPCA), which must typically be submitted annually. Estate planning is particularly complex because foreign assets may be subject to forced heirship rules, foreign probate, and reporting requirements such as FBAR (FinCEN Form 114) and IRS Form 8938. Those considering renunciation should understand that the process is irrevocable and may trigger the IRC Section 877A exit tax for 'covered expatriates' meeting net worth or income thresholds (IRS, 2024). The State Department fee for renunciation is currently $2,350, and the act requires appearance before a US consular officer abroad. Dual citizenship is permitted under US law but may create competing tax, military service, and inheritance obligations under foreign law.
Key Points
- 1US citizenship is retained indefinitely abroad and can only be lost through specific voluntary expatriating acts listed in INA Section 349 (state.gov/loss-of-us-nationality)
- 2Overseas voters must submit a Federal Post Card Application (FPCA) each calendar year to receive absentee ballots under UOCAVA (FVAP.gov)
- 3US citizens must file Form 1040 annually on worldwide income; Foreign Earned Income Exclusion for 2025 is $130,000 per qualifying individual (IRS Rev. Proc. 2024-40)
- 4FBAR (FinCEN 114) is required when aggregate foreign accounts exceed $10,000 at any point in the year; Form 8938 thresholds are higher and vary by filing status
- 5Renunciation requires in-person appearance at a US embassy/consulate, payment of the $2,350 fee, and signing an Oath of Renunciation (state.gov)
- 6'Covered expatriate' status under IRC 877A triggers a mark-to-market exit tax if net worth exceeds $2 million or average annual net income tax exceeds the inflation-adjusted threshold (~$201,000 for 2024)
- 7Foreign wills may not be recognized in US probate and vice versa; many practitioners recommend separate situs wills for assets in each jurisdiction, coordinated to avoid revocation conflicts
