Good luck!! Keep ringing. I had luck yesterday calling right at the end of the day, but I usually get that call volume message as well.
Our landing was fairly straightforward but I was so nervous about it! I had my letter of employment, sponsorship approval letter and proof of private insurance for 6 months ready to show them. We got pulled aside to a secondary interview area because we had said on our customs paperwork that we would be staying for approx 6 months. The agent just seemed really confused when I explained the situation about my husband and son "visiting" but also hopefully getting PR while visiting. She called over her supervisor who was super nice and totally fine with it. He just said "just be sure to leave the country when you are legally required if nothing is sorted yet". Once we get the 'in progress' statement on ECAS, we have implied status and they won't need to leave, but it also means my husband can start the process of getting a drivers license and medical cover in BC.
Can or can't ?
