I searched google.com about I-485 transfer from a center to another center and I found that it is likely that when you change jobs.
Some I-485 may be transfered to a local center, some maybe transfered to another one of the 4 big centers. Some people are lucky and I 485 was not transfered.
If it is transfered, hopefully, officers could process all the I-485 based on priorty date. Otherwise, my case will be the last of the 485 list after September 30.
I do not know. If you know that would help. Thank you.
