She can go now and ask for it to be withdrawn. The tough part is going to be whether a judge would be willing to see her today or whether the judge will just wait for her to annouce a withdrawal at the hearing.
At some point in the future, you may want to go to some online background check sites and see if the TRO shows up in a background check of yourself. This one allows for a personal pre-employment background check: http://www.fullsearch.com/
However, please know that a TRO is a civil petition and so it should not show up on a criminal record, so long as you do not violate it. Also, since a TRO can be obtained ex-parte based on mere allegations, it would be unreasonable for anyone to rely on it to deny you employment.
There was no due process when the order was issued. The due process occurs at the court hearing and you may want to have a lawyer present to make sure that it gets defeated from being a final protective order which could be damaging to your career/record.
Getting things in to evidence and keeping them out of evidence is why I recommend that you retain a lawyer because you can lose a case on procedure even if substantively the facts are in your favor.
See the bill that is being sponsered in MD to allow the expungement of domestic violence TRO from your civil record:
I think a similar bill proposed by the House was defeated in March.
You may want to have your attorney request that the court issue a specific order to have the TRO expunged from your record based on the Senate bill that is being contemplated.
