回复：有效，入境时同时出示新旧护照，新护照上应该有旧护照的号码。

我刚刚在美国大使馆网上找到一个信息：
I have a current visa in an expired passport and a new passport, can I travel to U.S.?
- Yes, you can travel to U.S. with two passports. As long as your current passport will be valid for 6 months from your date of entry into the U.S. and your previous visa will be valid the day you enter.
请问按护照破损，宣布作废的旧护照是与过期的旧护照一样能保证里面的签证的有效性吗？
谢谢!
