Hello! I am.sponsoring my spouse inside Canada . I have two kids (not from.him) . My job is not the 8-5 one and. I am a bit worried. I only have proof of my uber income. Which is not much and my child tax benefits..should.i write them.a.letter of explanation ..once he gets the work permit he will work as well ..but could.they refuse because i (the sponsor)have two. Small kids and not enough income also many loans..
