There is no current use of mediation in immigration issues so far that I know.  If there were a case, a competent immigration professional would be more knowledgeable than you or I.  Unless you are an immigration lawyer of course.

And no...the guy is a judge.  Apptd by Mr Obama.  He passed the bar and all.  Now Kagan?  That's a different story.  Never was a judge but got to SCOTUS.

Also, no absconding allowed.
