I (21) am traveling to Mexico by plane with my younger sister (11) to visit family. We leave in two days, but just found out that her passport is expired. We are both US citizens. With her passport expired, will she be able to come back to the US if we take her expired passport and provide other documents that prove she is a citizen, such as a birth certificate and SSN?
Please help, I don’t think there would be enough time in two days to renew her passport and get it back.
