So I went through this same scenario. Make sure you have a noc O A or B job before you apply for a spousal open work permit. IF NOT, IT WILL BE DENIED. My husband was a student and I got an spousal open work permit but the moment he graduated and got a PGWP, my open work permit extension was denied. My husband had to have a NOC o a or b job. Another thing I will advice is please please please apply for visitor visa for your wife. Do not let her run out of status.
