When Can You Be Stripped Of Your Citizenship?
Citizenship revocation is extremely rare and reserved for the most serious offenses. So when can a country revoke your citizenship?
In most countries, there are two ways of obtaining citizenship: guaranteed birthright or legal naturalization. Either way, it's relatively rare for a government authority to strip a person of his or her citizenship, unless they publicly disavow it themselves. For those who are "naturalized" citizens, the rights of citizenry can be taken away if it is proven that you deliberately misrepresented information about yourself that could have caused your application to be rejected in the first place. If a person has any ties to organizations that are subversive or advocating the overthrow of the U.S. government, that is also ground for having citizenship revoked. For people born into citizenship, there are certain actions that will cause it to be revoked, provided that you committed those actions with the intent to lose your citizenship. These include joining a foreign military that is in an active conflict with the U.S. Still, as detailed in this episode, it is a relatively difficult process to completely lose one's citizenship.
