Since your I130 petitioner is a PR and not Citizen, you might be adversely affected as a result of this Policy Memorandum published in July 2019, assuming you reside out of 6th and 9 th circuit.
Prior to this memorandum, Bennedict’s response would have been mine too.
Lawyer would be able to make closing remarks at the end of the interview, but I doubt on their ability to sway officer in either direction, with fact being there as it is regardless.
The memorandum however might not be applicable in your case as you have an advantage of being paroled by actual travel rather than afforded by virtue of being in TPS.

Good Luck
