we have applied in cairo (dcf) we need to know where is our case at now?
there s no site or phone so we can inquire about it?

DCF processes the case at the state department level, bypassing the normal USCIS process, so there is no online service to monitor the process of the petition.

All you can do is perhaps contact DoS and ask for status.
