Security Regulations

Our security personnel will only screen visitors who have business with the American Citizens Services unit through the security checkpoint at the front entrance to our building.  When the security checkpoint reaches its maximum screening capacity there are delays entering the building.  This now happens frequently and interferes with those who have appointments or face legitimate emergencies.  U.S. citizens are not allowed to enter the Consular Section with visa applicants unless they meet specific requirements and have advanced authorization from the Visa Unit. 

Embassy security procedures require that all visitors receive a security inspection. You will be allowed to check one cell phone at the Embassy gate but the US Embassy and local guards are not liable for any loss or damage to your cell phone while it is checked.  You will NOT be allowed to enter the U.S. Embassy for your appointment carrying any of the following items:

  • Any other battery-operated or electronic devices such as computer tablets, digital diaries, pagers, cameras, audio/video cassettes, compact discs, MP3s, floppy disks, laptops, or portable music players.
  • Any oversize shoulder bags or purses.
  • Any oversize handbags and travel bags, large back-packs, briefcases, or suitcases. Applicants can only carry in clear bags containing papers needed for their appointment
  • Any food item (a coffee stand with snacks is available).
  • Sealed envelopes or packages.
  • Cigarettes / cigars / match boxes / lighters.
  • Any sharp objects such as scissors, pen knives or nail files.
  • Weapons or explosive materials of any kind.

The list provided above is not exhaustive. Other items may be prohibited at the discretion of security staff.  Other than the one allowed cell phone, the U.S. Embassy will not accept the storage of any of the above prohibited items.  You will have to make alternate arrangements to store these items before you enter the Embassy.
