It is NASA's policy to offer a comprehensive health services program for international travelers to safeguard the health and productivity of NASA employees on international travel and duty assignments. The NASA Occupational Health clinics prepare NASA employees from a health perspective by providing health evaluations, immunizations, and information on diseases, food, water and personal safety in foreign countries. The clinics follow the guidelines set by the CDC and WHO.

For further information on the Agency's international travel policy please consult:

• NASA Interim Directive (NID): Health Services for International Travel or Assignment
• NASA NPR 1810.1A - Health Services for International Travel or Assignment .

Medical clearance by a NASA health unit clinician is a pre-requisite for clearance to travel on NASA official business.

Please refer to the OH's general information for foreign nation travelers page for more details on NASA rules and resources available to civil servant and contractor employees.

More international travel resources are available under the "Resources" column in this page. Both the CDC Traveler's Health and Department of State's Travel and Business websites offer a wealth of both health and safety information for the international traveler.
