According to an entry by USCIS Acting Deputy Director Mike Aytes in the agency’s Leadership Journal: “We attribute the increase in adjustment application filings to a couple things. First, customers’ anticipation of USCIS’ filing fee increase in July 2007. Second, a unique opportunity for workers and their families to file adjustment applications based on the visa availability date announced in the July 2007 Immigrant Visa Bulletin. Many of these availability dates have since reverted, creating a backlog of adjustment applications that cannot be adjudicated until a visa becomes available.”
