回复：我现在Ｈ１身份，４８５已经交了，passport已经过期一个月，忘了续了，马上去，那么有间断会对我有影响吗？ 谢谢

I think it's OK as long as you stay inside the US. But it's better to have a valid passport. Based on the new rule, you can not renew your passport anymore. You have to visit Chinese embassy or consulates to apply a new one. Here is a link for more detail: http://www.china-embassy.org/chn/hzqz/hzlxz/default.htm. Good luck!
