65 not reimburse these costs separately. If experts are concerned about using their foreign bank accounts, the option exists for experts to open a local UBS account. UBS waives bank charges where a minimum of SwF 6,000 is transferred into the bank account in a calendar year. Otherwise UBS will levy service charges, which are not reimbursable by OHCHR. 20. Experts may open local (Swiss franc) bank accounts at UBS in Switzerland into which the United Nations can transfer their DSA disbursements. Attestations will be provided by OHCHR to experts who wish to select this option. The attestation, which should be requested from the Office, must be presented to the UBS office at Palais des Nations when the expert requests to open a bank account. Because of bilateral banking agreements, American citizens who reside outside the United States who wish to open an account are required to present their individual attestations to the UBS headquarters in Geneva, located at 8 Rue du Rhone. American citizens who reside in the United States may not open bank accounts in Switzerland. 21. In line with United Nations rules, an advance of 75 per cent of the applicable DSA for short-term missions to Geneva and field visits will be provided via a bank transfer. For any mission that starts in Geneva and is followed by a field visit, the entitlement will be provided via a bank transfer. The remaining amount of the entitlement will be reimbursed on the basis of a travel claim submitted after completion of travel. The Travel Unit provides advance information on the approximate DSA amounts for field visits. 2. Terminal expenses 22. In addition to DSA, the traveller will receive terminal expenses for transportation to/from the air or rail terminal for each part of the official trip. Terminal expenses are not provided for an intermediate stop that: (a) Is not authorized; (b) Does not involve leaving the terminal; or (c) Is exclusively for the purpose of making an onward connection. 23. The standard payment for terminal expenses is presently $38 per transit on departure and arrival, except for New York City, which is $63. This figure is reduced to $11 when an official United Nations or government vehicle is made available for any part of the trip. 3. Travel claims 24. For all field visits and ad hoc missions to Geneva, experts must submit a completed travel claim to OHCHR within two calendar weeks after completion
