Existing or operating outside the scope or authority of a bureau or government agency.
From Latin 'extra' (outside) + French 'bureau' (office, desk, from Old French 'bure' meaning rough fabric used to cover desks). The term emerged in administrative contexts to describe activities beyond official institutional boundaries.
Governments have agencies called bureaus that handle specific jobs—extrabureau describes anything happening outside their official control, like underground operations or independent work.
