Earlier this month the Directorate of Defense Trade Controls (DDTC) released the new Advisory Opinions Application which is supposed to offer users faster, more convenient submission and status tracking. The application can be found in the Defense Export Control and Compliance System (DECCS).
All current DTrade Super Users with valid email addresses will be automatically enrolled in DECCS in the coming weeks and receive an email to activate their DECCS accounts in order to use the new application. If you are not a Super User, or do not want to wait to receive your account activation you can enroll and create a new DECCS account at: https://www.pmddtc.state.gov/?id=ddtc_kb_article_page&sys_id=652e00b7db78d300d0a370131f961946.
