Mandatory portal registration for AEO-LO applications, enabling online filing and real-time monitoring with a transitional physical filing allowance. The updated AEO LO web application requires applicants who have filed physical documents at the jurisdictional AEO cell to register on the portal, upload relevant annexures, monitor processing in real time, and respond electronically to deficiencies; a short transitional period allows continued physical filing without registration, after which portal registration is mandatory for certification, with existing manual applications remaining eligible for continued manual processing unless migration to the portal is requested.
