well i dont know it depends here is one intresting story... last time i heard on the FM that radio station organized a sweepstake in chicago.. The winner would get a new car.. and turns out.. an illegal immigrants wins it lol! she claimes it.. but they deny it to her.. thus she argues with them and thretens them to sue the radio station... in returns she gets scared as they would figure out how to deport her.. .. Thats was the case.. if i were you and an i was dealing with million + $$$ (Sounds good isnt it?) then i would rather take a safer route.. ask someone trust worty.. to claim it.. who is a us citizen.. or a legal resident... ps: make sure you compensate who ever claimes it..coz they aint gonna get nothing in their tax return.. infact they are goona pay.. lol
