His question was: So my question is can i apply for LMIA for the current position i am working at?
I meant that the employer will have to create another ad position (same position and name), and go all through the LMIA process.
If the candidate has or not a work permit, it doesn't matter. This is not relevant for the application. The LMIA will evaluate the market impact for the position requested and not if the candidate has an open work permit or whatever.
So, he can apply for a LMIA, but this has nothing to do with the position he is working at. Indeed, the employer should be looking for a Canadian employee to fulfill the position and apply only if he didn't find one.
