In conjunction with the redesign of the legacy e-filing system and transition to ELIS, USCIS has changed the process for paying the USCIS Immigrant Fee online. The revised payment process aims to “reduce the amount of information an immigrant must provide to USCIS.” In addition, anyone, including a family member, friend, employer, attorney, or accredited representative can pay the fee on behalf of an immigrant. All that is needed is the immigrant’s Alien Registration Number (A-Number) and DOS Case ID.
