Hi there josephinecudisal,
Before i got married to wife, she's also holding a work permit under the live in caregiver program. She worked with her employer for 8 months only because they don't need a nanny anymore. We got married last August 2013. She moved in with me after the wedding. Before she left her employer she was then 4 months pregnant (this was not the reason why she ended her contract so early). Since she lost her job, she filed Employment Insurance while looking for another work as nanny under LCP, but coudn't find one.
Its really up to you if you want to leave your current job, but you can't apply for other job unless you have your open work permit.
I sponsored my wife through family class. We submitted our spousal application plus her OWP application last December 31, 2013 at CPC-V. The current processing time for INLAND APPLICATION is 8-9 months if I'm not mistaken.
I hope this will help a bit.
