please you do not scare from these bullshits . go find another job. Since you were working on cash he dont have any record of your employment . he is just scaring you . Just ignore his fone calls. Police dont take these kind of shit since you havent done any crime . USCIS will not be looking any individual CD send by a person in mail. Lottery Commision will start investigating your boss first and might call the police for hiring illegal workers on cash and letting them to play lottery. thanks
