United States Citizenship and Immigration Services (USCIS) released comprehensive statistics [PDF version] regarding the processing of the Form I-485, Application to Register Permanent Residence or Adjust status. The statistics cover the period from July 1, 2015 to September 30, 2015. The chart contains statistics for each USCIS Field Office and Service Center that processes Form I-485s, and for each displays the number of received, approved, denied, and pending Form I-485s. In addition, the chart separates Form I-485s into family-based, employment-based, humanitarian-based, and other applications. In total, USCIS approved 157,110 applications, denied 11,800, and had pending 418,907 as of September 30, 2015. I have included the chart below for your convenience.
