I received my RFE for IMBRA. It was three pages of data, but really on the three newly required questions.
My application status never was noted with a "touch". I never received an e-mail that an RFE would be coming. I just found it in the mail.
My RFE stated that I had until 9/18 to submit the requested information. I sent mine back right away, but I would suggest that everyone else that receives these from CSC take several months to check, double check and triple check their information. In fact, there is no reason to rush in sending the information back. If the folks at CSC are bored and my form is the only one they have to work on, this is okay with me.
