入境时，如果间隔不到1年，可否和入境的官员说是USCIS寄丢了？非常感谢！
-If you return to US within one year, you just need to show your green card, not reentry permit is needed. Of course, you may bring the reentry permit approval notice (evidence) and explain that the reentry permit was lost during the mailing from USCIS if the IO asks in the port of entry. Your wife may go to the local USCIS Office in US to see how to solve this kind of issue.
