You will receive the benefits and higher tax rate. However when you file your income tax IRS will want to know about the other income and when they check it they will find out that you have questionable income so you may end getting a prison time for tax fraud. Itâ€™s not really a good idea. You can talk to attorney immigration services to discuss this matter and help your friend getting a visa as well. An immigration attorney can help you understand the laws and can help you increase your chances of getting a visa and other legal documents approved.
