Oops! Sorry for the miscommunication I had saved my forms with the wrong numbers.
For the travel form, I submitted only one copy with my wife’s name in section 1, her travel records in section 2a and mine on section 2b. My travel history needed extra space so I attached a separate page with my wife’s name, the form name, the section (“2b”) and added a table with the additional information.
I submitted only 1 IMM0008 form and listed her as my dependent. I did not submit one with her listed as primary.
In my case I kept UCI number blank for her. It will be generated once spouse/common-law partner gets added to your profile in the portal. They do that once these documents that you submit now are reviewed.
Please feel free to ask any questions you may have. We understand the stress that adding to spouse takes during this process having gone through it ourselves and we are happy to help!
