So...this is rather strange and I thought I'd reach out and see if anyone in the community has had this happen to them. Since creating my account back in late April, I have been on here reading and checking my account for the latest updates. Yesterday, I noticed the date for "submitted" had changed from the 22nd to the 25th. I originally sent my petition in on the 19th and received a mailed notice on the 22nd of April and that's what I put in my time line and what has shown every time I go to check my status. But today, upon checking to see if I had been approved after an RFE, I noticed the date for original submission had been changed to the 25th! Does anyone know why that would have happened and/or if it has happened to any other couple. Dates suddenly changing several months into the process? Just wondering....
