I am also being processed at California and I am a USC filing for my husband who is still in Nigeria filed online May 1 2021 PD , online confirmation said Nebraska but after I went into active review on May 5 2021 I reached out and asked Emma and was told it was at CSC and had been from the start .. today was told yes it was at CSC .. I asked for an expedite and the first time was denied without RFE but when I asked again this time they sent an RFE I just got today ..
