There is no such thing as an immigration pardon. I have never heard of "let's make a deal" in an immigration law context.

You have no standing to do anything, actually, in a legal sense, and as a foreign national barred from the US there is no way he could appear in a US court. Kind of a catch-22. You might find some loophole talking to a good immigration attorney but chances are you will just be bled for as much money as possible with no results.

Enjoy your visits to the DR.
