In the United States, citizenship can be revoked only on limited grounds, such as fraud committed in the citizenship application or service in another country’s military. Arguably, joining a terrorist organization hostile to the US is even worse than joining a foreign army, because terrorist organizations are more likely to target civilians.
在美国，只有有限情形才能被剥夺公民权，如在申请公民资格时弄虚作假或在别国服兵役。可以指出的是，参加与美国敌对的恐怖组织比加入外国军队还要糟糕，因为恐怖组织更有可能针对平民。
