Thanks for the quick answer!
I think I'm following you here - this is great. So, because I answer my kids in Point 6, I will have to provide details on the back of the page. I guess the "details" requested would be their names, their relationship to me (child) and their age. That should be sufficient I guess.
Follow-up question later in the same document. Question 14, employment history. For each line, I am to provide "family size". Do I fill in 4 (myself, my wife and my 2 kids) or 6 (myself, my wife, my 2 kids and my 2 parents that I'm hoping to sponsor)? I think the family size in my case is 4. Do you think that is correct?
Ans : while you type every tax years income each line , type your current family size for that year. You don't need to add your parents. ie, in 2014 if you had only one kid, your family size was 3. Next year in 2015 you had a baby. Means your family size for that tax year would be 4.
