U.S. citizens can live abroad indefinitely without losing their citizenship, as it is generally a lifelong status that cannot be lost simply by staying outside the country, regardless of how long. There is no legal time limit for maintaining citizenship while living overseas. However, you must still file U.S. taxes.
No, you generally cannot lose U.S. citizenship just by living in another country, as it's a permanent status; however, you can lose it through specific voluntary acts like formally renouncing it at a U.S. embassy or by performing certain actions with the intent to give up citizenship, such as serving in a foreign military against the U.S. or committing treason. Prolonged absence doesn't automatically revoke citizenship, but maintaining ties like filing taxes and visiting helps prove you still intend to remain a citizen.

The U.S. Citizenship "3-Year Rule" allows Lawful Permanent Residents (Green Card holders) married to U.S. citizens to apply for naturalization after only three years of permanent residency, instead of the standard five, provided they've lived in marital union with the same citizen spouse for those three years and meet other requirements like continuous residence and good moral character.

It is recommended that you apply for a reentry permit if you plan to be out the country for 6 months to one year. For any trips longer than one year, a reentry permit is required.
