My 140 was filed at TSC and after 1 month it was transferred to California Service Center.
It was at the California Service Center for 9 months before my attorney raised 2 SR's and yesterday the status changed to:-
"The I140 IMMIGRANT PETITION FOR ALIEN WORKER was transferred and is now being processed at a USCIS office. You will be notified by mail when a decision is made, or if the office needs something from you"
I am not sure where this is transferred now, is it gone back to TSC or somewhere else. Just wondering what could be reason for multiple transfers?
