how many i-130

[shaman]

I am US citizen and I want to sponsor my sister's family(4 person) from canada for Green card in the family based immigration.
should i submit 4 separate sets of (i-130) forms one each for my sister, my bro-in-law and two for my 4 year and 2 year old nephew ?
how much should i pay $355.00 filing fee X 4 = $ 1420 ?
any other form i need to fill with i-130?
thanks

One I-130 for your sister. Mention everyone else's name in her I-130 petition.
