Hello we are currently usa residents and I have submitted our application for me and my spouse and is waiting for the next step. Provided the application gets approved do we have to do the landing together in canada? My spouse is planning to visit her home country in the mean time and wont be returning to usa, but I will be in usa. How do we synchronize our landing process , any advice? Also when do i need to let know cic about my spouse's travel plans and change of address as she may have to use her home country's visa office.
