Applicant in spousal sponsorship from Outside of Canada is visiting/living in Canada with her husband and children while she waits. She travels back and forth to the USA about once every 1-3 months. Last entry she was given a visitor record for 1 month and told to renew it online. If she leaves before the VR expires, can she just re-enter Canada on her next visit and start again? Or must she renew it? Can she travel back and forth while waiting for renewal? Can she travel back and forth once it has been renewed or does each exit start a whole new process?
