AINP Questions Obligation to employer that nominated you

[Phil-Canada]

My Girlfriend has applied for her AINP and has her file number now.

Is she obligated to stay working for that employer ? If so for how long?

She would like to move to BC so we can be together. Can she move to BC if she is granted her AINP and PR. ?

If not how long would she have to wait to move to BC after getting PR.

Thanks
