Hi Guys,

I am filling i-485 for my wife and my parents.

Ill sent my wifes i-485 out first with form i-864 (affidavit of support), Do i need to fill out form with all the three name (my wife and my parents) or is only my wifes name is enough since Ill send her application first

Also my anual salary is 65k, Is enought to support 3 peoples? I saw it i-864p.

It say household of 4 person need 25K, Mean I can support 3 people with 25k , or each person need $25k , which 3 people is 75k?

Thank You guys in advance
