老妈把护照上签证过期日期看错了，现在已经过期了，还有办法吗？
-She/you need to contact or go to see the US Consulate in Guangzhou that issued the visa ASAP and plead her case. Thus, probably she maybe able to have the visa reissued but that is not guaranteed. May need to pay the statutory fees for an application and an immigrant visa agian.
