That's interesting request since Eb1a applicants do not have to submit the
Supplement J form according to the instruction.
===========
"NOTE: Individuals seeking or granted a National Interest Waiver of the job
offer requirement and individuals seeking or
granted classification as an alien of extraordinary ability under INA
section 203(b)(1)(A) do not need to file Supplement
J. Because these employment-based immigrant visa categories are not tied to
a specific job offer, individuals seeking or
granted classification as an alien of extraordinary ability or seeking or
granted a National Interest Waiver of the job offer
requirement do not have to file Supplement J when filing Form I-485 or to
request job portability under INA section 204(j)."
