do you have to be related to some one or can you be a friend and sponser some one ?????????????????????

[PraetorianXI]

Anyone can "invite/sponsor" you to come to the US. It does not have to be a relative.

Even without being invited, any body can apply for a visitor visa. Only thing is that he/she should have sufficient ties in home country to come back after the visit. It is better to have sufficient bank balance, properties etc and shown to the VO at the time of interview.
