请问如果小孩的美国护照过期，从加拿大回美国， 用美国的出生证明可以回美国吗？
-Your child had better renew the passport in the US Embassy/Consulate in Canada. If your child has no choice, he/she may just try to use the expired passport and the birth certificate to enter US by land.
The following is copied from the US DOS website:

When returning to the United States from Canada, it is very important to note that all U.S. citizens are required to present a valid U.S. passport to enter or re-enter the United States via air. For entry into the United States via land and sea borders, U.S. citizens must present either a U.S. passport, passport card, NEXUS card, Enhanced Drivers License, or other Western Hemisphere Travel Initiative (WHTI)-compliant document. The only exception to this requirement is for U.S. citizens under the age of 16 (or under 19, if traveling with a school, religious, or other youth group) who need only present a birth certificate (original, photocopy or certified copy), Consular Report of Birth Abroad, or naturalization certificate.
