hi, im applying to visit my sister which is canadian PR, im going with my spouse and 2 kids, for myself i selected "im visiting sibling" option and for spouse and kids i chose visit other family or friends, for them i need to upload invitation letter but for myself i could not find any place to upload invitation letter. I also could not find a place to upload documents regarding my employment letter or any other documents to support my ties to my current country of residence. should i just proceed with the current application and wait for officer to request for additional documents?
