What are 3 ways to lose your citizenship?

You can lose your citizenship through: 1) voluntary renunciation, where an individual formally gives up their citizenship, often to acquire another nationality; 2) being convicted of certain serious crimes, such as treason or espionage, which can lead to denaturalization; and 3) residing outside the country for an extended period without maintaining ties, which may result in the loss of citizenship in some jurisdictions. Each country has its own specific laws governing these processes.
