I received a RFE one week ago with a 30 day period too. It asked for my hu*****and's employment letter (he is the main NIW applicant and got his green card September 2006).
Is it normal asking for spouse's employment letter one year later to support dependent's pending I-485? He changed his job very recently. Will the IO ask for more RFE? This is the second RFE from IO in NSC -- the first one was in last October for our marriage certificate.
Thanks a lot!
Happy holidays!
