Form i-864 Part 5, Household size as it pertains to children.

[ksoo]

·I am filling out an I-864 and petitioning for my wife. I have come to part 5, question 4 in Household size and the question states "If you have dependent children, enter the number here. I do not have dependent children but my wife has two dependent children. I have never claimed her children on my taxes but they do obviously live in our household. Should I enter them in this question as "2" even though I don't claim them as dependents?

Thanks
