Do you know how many H1Bs are issued per year? Do you know how many jobs are lost per year? Do you know how many jobs are created by immigrants (and their kids)

Do you know how many H1Bs are issued per year? Do you know how many jobs are lost per year? Do you know how many jobs are created by immigrants (and their kids) who started out on H1B? Do you know how much tax revenue comes in from H1Bs and how many social programs they support? Sorry about your friends, buy H1B here is just a boogeyman.
