Hey! Don't get anxious over later dates getting AORs before you. Most agents work in chunks ( so can be files across a week or two), some agents faster than others.I am march 6 and still waiting
If you look at the general progress on AORs for March applicants, you will see there have been more of those in this shortened week than in more than a week before. So at that rate, most ( if not all ) of March applicants will have their files acknowledged before end of this month.
