In my case I sent the I-30 for my husband. I received the IOE text on August 21, and then a month after I called I found out they sent the NOA1 to a different address and that the case was being processed on Nebraska. A month later I called again and told me they corrected the error and that the case was never on Nebraska but on Vermont. Turns out that I received a letter about the correction and it came from Nebraska. Still I haven’t receive any other document or notification I’ll have to call them mid this month.
