Thanks for your response i really appreciate. they have two kids. tuition is CAD19,000 and the husband have about CAD58,875.70 in their bank account in nigeria. though they have paid CAD2,200 tuition deposit already to the school.
i also wish to enquire if its better for the wife to apply for the OWP for the husband while applying for her study permit or wait when she gets her study permit she will then apply for the OWP of the husband while in canada.
