I hope this is a good sign. It took a little over a month for us to get our Notice of Action with our I-600a! This time it was mailed on 10/15, received in Texas on 10/19, dated 10/21 and postmarked 10/22! To me that is quick!
So, our paper work should now be on its way to Newark, NJ. Hopefully we will get a speedy approval! And I also think that this Notice also means that all of our forms were completed correctly and we don't need to change anything or submit anything else. Fingers crossed!
