just be careful how you make and what you do to your earnings... IRS knows everything.. don't try to fool them... you can get away from anything in this country but not the IRS. and they are not going to believe that you are working 100-120 hours a week in two different places. They would rather spend thousands of dollars to get hundreds from you. -> personal family experience. you can have the indians pay cash to your wife, bhai and buhari.. even after taking the tax out if that indian wants to.. but you do not want to report that in your ssn. yes, it will affect your green card applicaiton from your other employer. until last year INS and IRS were two separate things and still are.. but now they will be sharing their database. so, just don't do anything that your heart says not to unless you want to screw things up...
