My husband and I filed I-130 for me and about 40 days later we filed I-129F for K3. The receipt we got for the I-130 said it’s at the Nebraska Service Center. Meanwhile, the receipt we got for the I-129F shows that it’s at the Texas Service Center (SRC are the first letters of the receipt #). My question now is this: does this mean that our filing is transferred from Nebraska to Texas? Are these two filings always processed at the same service center? I ask because according to USCIS website, different service centers have different process timelines and it seems Texas is one of the slowest ones.
