You can make an application seeking permission for him to return to the U.S. after deportation. Once that is approved, you can sponsor him to become an Permanent Resident. These cases are very complicated and you must be sure that he is likely to qualify before making the application. As such, please schedule a consultation with an attorney and gather as much documentation as you can from his deportation so that you can review them with the attorney.
