I got my greencard in 07 and moved to a new residence Jan 08. I have updated my address etc. with UCIS. My brother's company is sponsoring his green card as well and we live in the same household. Recently some person from my wife's families side asked her for our address as he wanted a package sent regarding business here. To my surprise he has applied for immigration for his son on our address without asking us or letting us know. Neither my wife nor I know them but apparently my wife's parents do (they were unaware as well). I plan on sending the UCISC receipts back saying addressee doesnt live here; RETURN TO SENDER. Are any of these events going to hinder my brothers green card or mine when I file for permanent residency (I am on a conditional gc) in 09? Should I call someone and report this? Thank You.
