It is important to keep receipts of all money exchanges, as these frequently are required upon departure. Declare such items as cameras, radios, etc. to preclude possible explanations, customs charges, or confiscation when you leave. Contact the American Embassy or Consulate prior to your arrival and provide your local address and length of your visit. For most official business visits, a cable should be sent to the appropriate embassy advising of your visit. Use of public transportation is recommended rather than driving yourself.
Many countries deal harshly with foreigners who are involved in traffic accidents.
Taxis are the preferred mode of transportation. State Department advisories provide updated information regarding public transportation in the country you are visiting. Avoid clothing and other outward vestiges which unnecessarily advertise you as an American citizen. Although you are an American citizen, you are subject to the laws of the country in which you are traveling. Use your best judgment to avoid any situation which may allow a foreign intelligence service the opportunity to blackmail or coerce you.
