My 140 was approved by TSC and I am going to file the 485 now. On the 140 approval notice, it is said that the Form I-485 should be submitted to *THIS* center (presumably the TSC). However, when I read the instruction for I-485, it says that residents of California should file their I-485 to NSC. I am confused and don't know where I should submit my application. Can anyone help me? Thanks.
