I am currently in US with a green card. I am currently engaged to my fiancee (she is still abroad with no US status) and once we get married I am planning to get her here, it takes around 2 years I think for her to get the visa. Recently one of my friend (with family of 3) won a lottery for diversity visa and needs sponsoring and asking for help. If I sponsor him before I bring my fiancee (would be my wife then) would it hurt my chances or cause any impact once I start the process of her bringing here? Would I have to mention if I have sponsored anyone in US in the I130?
