Hi

, I'm not sure if you ask about these dates but here they are:
08/20/2000 - VSC recived my application (my father applied on behalf of me when he was LPR)
08/20/2000 - my priority date
12/15/2004 - my father became USC,
01/06/2005 - we sent copy of father's naturalization certificate and cover letter to VSC to upgrade my status from F2B to F1,
01/19/2005 - VSC received documents and made update,
02/08/2005 - my petiton has been approved
02/18/2005 - we received letter from VSC informing us that case has been approved and all documents were fowarded to NVC.
Now I am waiting for the reply from the NVC.
I hope that these are the dates that you asked for

. if you have any farther question, just ask.
