Yes, many times the person in the MOC’s office notifying is different than person uploading the information. For most house members the nominations are handled through their “district” offices in home areas but because (at least used to be) the congressman / woman has to sign forms certifying the nominations, because of this some times the uploads to portals are from DC offices - and at different times. As in my son’s (2X) case he got a call after seeing it appear in his portal and never got a call with any of his appointments. it real just depends on the MOC and their office. If it shows in your portal I would take it as a sure thing! Good luck to you and thank you for your willingness to serve.
