請問: USCIS電話客服裏的人知道關於case的進展的情況會比網上顯示的多而詳細嗎?
Answer: They should know more current progress than USCIS web site, but not really the real situation.
If you call the USCIS' National Customer Service Center (NCSC), you can ask the information officer for an update on processing times. These people do not have complete information, but you can ask for the date of cases being processed at that time.
About every two weeks, the USCIS information officers get an update of these dates, so you may get a good idea of processing times. http://www.greencardapply.com/question/question.htm
