How to change the identity of a study mother in Canada

The accompanying mother has a ten-year multiple-entry visa. She can apply to convert it to an international student visa. If she does not want to convert it to a study visa, she can convert it to a marriage immigration visa, but she must divorce her domestic spouse first. Another option is to convert to a refugee visa. Note that the last method has the highest rejection rate when applying for a refugee visa, the highest approval rate when applying for a study visa, and it is also more troublesome to apply for marriage immigration.
