I do not know why you are not responding, but you are not charged per question, per response, nor per answer. So after I give you my answer, you can continue to ask me questions without additional charge until you are satisfied. I apologize if it is a site issue that you posted and the post did not go through.
The reason I am asking if you have explored the possibility of a governor's pardon or vacature is that IF he is not eligible for Voluntary Departure if he has been convicted of an aggravated felony, he may have to look towards those as options. Let's take this step by step. First, here is the law in regards ***** ***** departure:
(a) Certain conditions
(1) In general
The Attorney General may permit an alien voluntarily to depart the United States at the alien’s own expense under this subsection, in lieu of being subject to proceedings under section 1229a of this title or prior to the completion of such proceedings, if the alien is not deportable under section 1227(a)(2)(A)(iii) or section 1227(a)(4)(B) of this title.
We then go to section 1227:
(2) Criminal offenses
(A) General crimes(i) Crimes of moral turpitudeAny alien who—(I)
is convicted of a crime involving moral turpitude committed within five years (or 10 years in the case of an alien provided lawful permanent resident status under section 1255(j) of this title) after the date of admission, and
is convicted of a crime for which a sentence of one year or longer may be imposed,
(ii) Multiple criminal convictions
Any alien who at any time after admission is convicted of two or more crimes involving moral turpitude, not arising out of a single scheme of criminal misconduct, regardless of whether confined therefor and regardless of whether the convictions were in a single trial, is deportable.

From my reading of the law, your son MIGHT be eligible for voluntary departure. Why? Because from what I see, if he was not convicted of child pornography and he was not convicted under California Penal Code 288, then there is no aggravated felony against him. Since you have not responded, I have to assume that he was charged and convicted under California Penal Code section 288.2 and from my research, that does not make him ineligible for voluntary departure. If he was convicted of something other than 288.2, please let me know.
