Few Questions as i'm sure this may have been asked before.

Brother was given option to become resident 15 years ago and never completed it.
Parents were both here as residents.

Brother entered US 7 years ago by way of tourist visa, did something stupid and petition for residency on basis of extraordinary ability work wise 3yrs ago. Was denied, furthermore given court precedings.

He is now scheduled to leave by way of voluntary departure next month. His mother and father are both residents 26 yrs and me and my sister are US citizens, along with 1 of 3 of his own children.

I have already petitioned him as a relative a year ago and just received in the mail that the application is being processed.

Is there anything we can do to prevent his departure. I'm assuming he has a 10 yr bar of reentering
