I planned to apply for a new work permit before my current one expires, getting implied status and keep working while waiting for NSPNP and the application is being processed (roughly 100 days). After getting my nominee, I will be exempted from LMIA, thus I can update and process with my application doesn't matter if my LMIA would get accepted or not, and be able to keep working for the whole duration from after I get implied status until after getting new permit.
I am not sure under which NSPNP program you are planning to apply , and I am honestly not that familiar with it, but I would like to know under which program you think you would be LMIA exempt?
The timeline would be:
Request LMIA and apply for NSPNP --- apply for new work permit and get implied status --- old permit expires --- get nominee --- update my appication (which is now nolonger need LMIA) --- getting new permit.
During that time LMIA result can come in anytime but it won't change the steps.
You can try to "float" that way, but there is no real benefit any more. If you simply apply for a work permit without being eligible, your application can be returned as incomplete, and your status will expire with the original work permit - you will never have been on implied status.
However I still have question about that. You said I would get implied status "as long as the LMIA is approved", so just in case by the time LMIA came in and it's negative, would I stop having implied status the moment I get LMIA result, or would I not be able to get it from the start (which would make me illegal worker for the duration I worked as if under implied status everthough I have no way of knowing it beforehand), or would I be able to keep implied status until I have result for my new work permit application ? I couldn't find any information regarding implied status being reverted outside of "incomplete application"
If you apply for an LMIA-based work permit, and you do not get the LMIA, is it then not "incomplete"? Even if it is refused (instead of returned as incomplete), if the original permit has expired before you submit the 2nd application, you still have to apply for restoration, and implied status would not extend beyond the refusal of the first application.
