Google的结果： do i need a valid foreign passport to apply for U. S. citizenship? Even if you have not traveled outside the United States since becoming a permanent resident, you should bring all of your valid and expired passports and any travel documents issued by USCIS to your naturalization interview.
谢谢！
你知道申请入美国籍的时候是否需要提供有效的中国护照呢？谢谢
明白了，感谢！
记得入籍申请移民官会看一下护照和绿卡，过期问题应该不大，你也可以问问律师，我入籍都是10多年前了，现在什么情况不清楚
就是不清楚呀，所以才问问大家谁有经验可以交流

好吧，那还是得先去更新护照了
25号起使领馆开门，但护照还是只能在线上办
