Interesting question. Yes. If the son is in A-1 status, he will need to give up the privileges associated with the A status. He does this by filing certain forms with the DOS when filing the green card application. To ensure that your son does meet all of the requirements, however, you do need to have his case completely vetted by a competent immigration attorney. Do not use my email as the basis for moving forward as A cases are unusual!
