"My observation is that INS takes up different tasks from time to time. For example, it appears that they are doing EAD and AP now a days. EAD processing dates went from Jan to June in the matter of weeks. They should be bringing those people back to 485 soon."-goodsaint
INS is procedural and not object oriented.INS do not set priortiy between EAD , AP , or 485.There are people working on each of these at same time.The delay in 485 approval is not related to EAD,or AP processing.
