Sorry, but you are wrong here. Instructions are very clear and not just at one place but many, like, Checklist, Guides, IRCC website & in the forms.Yes missing signatures are a definite return of the application. Some people have said 4 weeks, others 3 months. It’s not clear how long it takes. It’s extremely frustrating, esp since the online instructions were not clear at all re signatures. If you withdraw will you have to pay again? It gets complicated with that too, and payment issues also mean a returned app.
