回複:VSC NIW RFE due Mid-June, should I file to VSC or new cent
In your RFE letter, there should be an instruction on the bottom of it telling you where you should submit the RFE materials to. I did mine on 04/21/2006 and submit back to VSC. This is also what my lawyer said.
hope it helps
Good Luck
PS. Could you share more info of your case? RFE content, IO number and NIW etc..
