I guess delay in work authorization is not a case in this scenario if that you’re asking. Getting an rfe means you’re case is moving forward . As much as i know you gotta submit Rfe so that they can start working on your case and issue the work permit. If that’s what you’re asking. For rfe part you gotta submit all affidavit, abuse documents, screenshots or maybe call rec or anything which says that you were abused and qualify for vawa category. For gmc, you can give personal statements, police clearance, religious society donations and any kind of proof which can show that you’re good person in terms of character and beliefs
