It sounds like your mother is currently a foreign worker - is that correct? Has she applied to become a permanent resident of Canada? Or is she in the process of applying? If she is applying to become a PR, then you will be included on her application provided you are still young enough and a dependent. It will take anywhere from a few months to a few years for the PR application to be processed. Once the application is approved, you will all have to come to Canada to "land" and officially become permanent residents. Once you have become a PR, you will have to live in Canada for three out of four years to qualify to apply for citizenship. It's currently taking around two years for citizenship applications to be approved once the application is submitted.
