Hello Andrea...Hello everyone. My problem is similar, I am student and my husband is worker. We both have our study and work permit respectively. We are trying to renew our visas, but after the online eligibility questionnaire on the site, the application generates the form IMM5257 for me BUT the form IMM5708 for my husband. Searching on the internet the form IMM5708 is not the correct one, I have checked my answers and everything is correct and matches what you have said before here. I don't know if this form is correct now or what it's happening... I appreciate your help and guidance
By the time I did my TRV... I asked here without answers. Finally what I did? So, I had to do all the process with something called "Temporary Resident Visa (TRV) from within Canada". Fill out all the forms, print and send it to Otawa, by Canada Post.
