My LC approval notice sent by Chicago DOL was lost in the mail. My lawyer talked to DOL and it looks like a duplicate copy will not be issued. My lawyer is filing for my I-140 without the LC approval notice and it seems the procedure is that BCIS would request a copy of the LC approval from Chicago DOL. Has anyone had a similar experience ? Please let me know. What exactly needs to be specified when I-140 is being filed without a LC approval notice ?
