How come a lawyer submit an LMIA for you? I think should be the employer do that. My employer submit LMIA for me and there is no such file number thing. We received approval letter after 3 weeks ( at the time a I was the 1st foreign worker needed LMIA). Well, Im not sure how it works now, but I think none of lawyer can submit LMIA for you, it must be the employer and now it take few months.
