69 Nations to provide appropriate security support in the event of a serious security development while the experts are on official travel. This security clearance is requested by OHCHR on behalf of the expert. III. ADMINISTRATIVE FORMALITIES 39. Immediately after taking up their functions as an expert, incoming experts are requested to provide to the Secretariat: (a) A photocopy of a valid passport (page with personal data and signature); in the event the expert holds multiple nationalities, a copy of the passport for the nationality referenced when the expert was appointed as a committee member, mandate holder, etc. should be provided. (b) Completed United Nations banking forms; (c) Request for UNOG security grounds pass; (d) Application for United Nations Certificate; (e) Certificate of completed Basic Security in the Field online course; and (f) Confirmation of place of residence. 40. A photocopy of the passport is necessary for the creation of a record for the experts in the United Nations information management system, which integrates all administrative functions within the Organization. This system is used to generate travel authorizations as well as payments. 41. As payments of travel claims through the information management system are made by electronic transfer into the bank account designated by the expert, each expert is required to provide their complete banking details (including the relevant international branch sorting code for their bank, e.g., IBAN/CB/RIB/ABA/etc.) through the United Nations banking form. Banking information should also be included on all travel claims. If this information is incomplete, the claim cannot be processed and the form will be sent back to experts and reimbursement will be delayed. 42. For the Secretariat to provide proper service, experts are requested to indicate their preferred working language among the official working languages of the United Nations (English and French).
