Hi! A friend of a friend has just won the DV lottery and asked me to become their sponsor for the consulate interview. I believe this involves filling out a form and submitting proof of income, etc. I am a bit hesitant to do it since I don't know the person and it looks like it's a big obligation. I won the DV lottery about 6 yrs ago and I am currently in the U.S. What are the implications of signing this sponsorship form for someone to guarantee funds, etc? Would the US government come after me if the person comes here and gets on welfare? Has anyone had any experience? Thanks for your help!
