Your citizenship could be revoked if, within 5 years of naturalization, the U.S. government proved you joined a subversive group. Such groups include Al Qaeda and the Nazi Party, for example.
Your citizenship could be revoked if, within 10 years of naturalization, you refused to testify before a U.S. congressional committee investigating your involvement in an allegedly subversive act. Subversive acts include trying to harm U.S. officials or overthrow the government.
If you lied or concealed relevant facts in order to obtain U.S. citizenship, your citizenship could be revoked. This is called illegally procuring citizenship.
