回複：急問：H1 Notice of Action寄丟了怎麽辦？

You can call INS and let them fax a duplicate to you if you need it immediately. However, you and your employer still need a original one sooner or later. I-824 will take you at least 3 months, and make sure INS put the correct address. If that was their mistake, ask them to remail it to you. Good luck.
