I think I have the same situation like her, my husband is the main case I'm his dependent. I have to travel out of country (just me) and come back soon. I searched, it looks no danger for me to come back as soon as my husband receive AOR. they will give us time for BIO without cancelling our Visa. Thought?Yes just in case when you got it at the time of leaving home country and did not returned there at all after coming to Canada
