I had submitted my I-130 to Chicago Lock box in November and subsequently filed the AOS on the 15th of Jan 2009. I checked online and found out that my I-130 petition was referred to Vermont Service Center. Today I recieved another letter(Notice of Action I-797C) stating that my case has been tranferred to California Service Center as they have jurisdiction over my case. Being a resident of NY, i am surprised why that is so. Is that common?Why would they transfer it while still in process? No details were given either in the Notice of Action. Anybody have any experience in this matter.
