Hi,
Does anyone know what the colors of the rows mean on the Processing Dates page of USCIS? For the I-751, sometimes it's green and sometimes it's yellow even though the posting date stays the same (right now Sept 19). Only the colors keep changing every couple of days.
Thanks!

All applications of the same form type are one color, then the next form type is a different color. It may change depending on what types of application are being processed (i.e. if there are more or fewer types of applications being processed).
