From personal experience, If you're a VAWA and one day you wake up and suddenly you encounter this type of status, or say you found out that an important letter, notices from USCIS was returned back by USPS for whatever reasons. Please, don't waste your time talking to Ombudsman, don't waste your time filing e-Request for a copy or writing letter to USCIS or calling or chatting Emma. They all won't help especially if you're VAWA. You'll waste your time especially if it's an interview or RFE or RFI.
Just go straight and write a nicely written letter to your Congressman/woman or Senator and they will help you, esp if it's VAWA.
You'll thank me later.
Happy new year to everyone.
