Thanks for Agent Life magazine for the following tips:

Before packing, discuss local customs.  While shorts and tank tops may be fine for many places in the US, they are considered risque by many cultures.  Plan outfits that will be acceptable by local standards.

Consider how credit cards, cash, documents and other valuables are carried.  Many teens aren’t used to carrying a purse or wallet and will need guidance. Discussing strategies for avoiding pickpockets is also appropriate.

If teens are flying alone for the first time, plan an advance airport tour and specifically identify where to find information and assistance.

Have teens carry a business card from your hotel, in case you get separated.  They could show the card to a taxi driver if they are unsure how to explain where the hotel is or don’t remember its name.

Discuss photo etiquette.  Many teens are accustomed to “selfie” culture, but light-hearted behavior is inappropriate in many places, particularly in religious sites and other sensitive areas.  Locations of military significance may also be off-limits to photography.  Also discuss photographing local people and how to determine whether it is appropriate.

Be sure teens know to stay away from protests and demonstrations of any sort.  Freedom to assemble and speak freely is not a universal right and teens may be unaware.  They could find themselves in serious legal trouble for watching or participating in any kind of public unrest.
