DHS is revising regulations that authorize the means to serve decisions and other notices in-person or by mail, to include electronic and other means of service. Current regulations limit ICE, a component of DHS, to serve documents in-person, or by certified, registered, or ordinary mail, which is time consuming, inefficient, and unreliable. This interim final rule enables ICE to issue and serve notices, decisions, and other documents electronically to noncitizens, parties, attorneys, or other persons of interest who voluntarily opt-in to be served electronically. The intent is to improve convenience, transparency, and provide quicker information and communication to both the public and the government without burden. This interim final rule also permits ICE to issue bond-related notifications to obligors electronically for immigration bonds. Initially, the Enforcement and Removal Operations (ERO) Bond Management Unit (BMU) will utilize electronic service. ICE ERO is developing the Cash Electronic Bonds Online System (CeBONDS) to allow obligors to conveniently post ICE immigration cash bonds online without visiting an ICE office in-person. This rule is consistent with Executive Order 14058, which directs agencies to take actions that improve service delivery and customer experience by decreasing administrative burdens, enhancing transparency, and improving the efficiency and effectiveness of government.
