USCISis discontinue its legacy e-Filingsystem and will be rolling out a new system called the ElectronicImmigration System.  A date for the launchof the new system has not been announced.
USCISexpects that the new system will be faster, more secure, and easier to upgradeand update.  Importantly, the new systemswill have high data security standards.
Thelast day to start new forms in the present system is August 30, 2015. The oldsystem will be decommissioned on September 20, 2015.  After September 20, all forms must be filedvia hard, paper copy. 
Thelegacy e-Filing system has offered online filing for several USCIS forms,although it was never widely accepted by users. MU Law rarely used the e-filing system, as it offered no tangiblebenefits to petitioners and had several detriments. 
Itremains to be seen if the new proposed system will enhance user experience.  It is worth noting that the Department of Labor’son-line PERM system just celebrated its 10th anniversary.  While the PERM system is not perfect, it achievesits goals and is a good model for the USCIS to emulate.
