When you apply for permanent residence, you must ensure that you still have a valid work permit and that you are working for the family for which the work permit is issued. Once you have received a favourable assessment of your application (approximately 6 months after its submission), you may apply for an open work permit. This will allow you to take any job you wish until you are granted permanent resident status. You will not receive your permanent resident status immediately. Normally, many people apply for permanent residence in Canada and you must wait your turn.
