7月底用AP回国，现在排期刚current,如果顺利，8月份有可能绿卡被批准寄出。到时人不在国内（原打算让邮局hold mails一个月），及绿卡的邮件会不会退回USCIS?
-You have a mailbox in your home, don't you? The mail will dropped into your home mailbox (USCIS normally send this kind of letter using First Class (not need your signature). You can ask your friend/neigbour to check the mail for you if you worry about the mail may be lost from your mailbox.
就怕到时候节外生枝，退回去的邮件被弄丢，不知道去哪里找了。多谢！
