So my wife and kids has a multiple visa. they came here last September so she can try to apply for a student visa and we bought them a two-way ticket for 3 months but the return ticket was never used. now that her student application is on process. she needed to go back home and leave or kids here with me to give her biometrics. so we bought her a two-way ticket . canada - philippines / philippines - canada. so is hse going to have a problem going back here in canada because basically he doesnt have a return ticket to his home country?
