Hey guys,
So I got a letter from CIC asking for more stuff today.(No AIP yet

)
I am another Sep 16 2013 person.
Could someone help me with the IMM5406 form?
I was told not to send it originally by someone, but I guess that was incorrect.
Anyways so my Canadian GF is sponsoring me, I am wondering how much of this form do I need to fill out?
We have no kids and I'm not bringing anyone with me. For the brothers and sisters section, do I need to include all my family back home?
Does my Canadian GF need to fill another version of this form too with her info?
Thanks in advance guys and sorry if this is a silly question.
