Hi
At USCIS web case status page
https://egov.immigration.gov/cris/jsps/index.jsp
you can set up Create/Edit customer portfolio account. Then everytime you log in you can check your case. If you have the receipt numbers you may add more cases to your account. Each time you logged to to these portofolio you can check last date each case has updated. By clicking further you can read the stutas. I noted that the status does not change when your fingure print has been received. But the last date updated will be changed. For example if the last thing you did is fingure print, it will appear the date the finger print was received. At least this is what I observed in my case. Try to set up this. I hope, it will be helpfull.
