USCIS recently began transferring some Form I-130, Petition for Alien Relative, cases filed by lawful permanent residents for their eligible family members from the Vermont Service Center to the California Service Center.
If your case was transferred, USCIS will send you a notice listing the transfer date and where your case will be processed. Your original receipt number will not change and this will not delay the processing of your cases except for the additional time needed to transfer the file.
Here is another question from one of our clients posted in our extranet forclients.com.
Qo. My Priority date became current as per August bulletin.
I and my wife are applied for I-485 on July 2007 (PF is done and got EAD and AP docs). At that time my son was in India and i could not apply for him.
Right now i am working on his I-485 paperwork and targeting to send his application to INS/Nebraska on August first itself (through your Law firm).
