Language: The official language of Gabon is French; if you do not speak French, you will face difficulties in communication associated with the language barrier.
Identification: You should always carry identification and proof of legal immigration status in Gabon with you in case you are stopped at a police checkpoint, such as a residence permit (carte de sejour), your U.S. passport, or a legalized photocopy of your U.S. passport biographic information page and your Gabonese visa page. City hall offices in Gabon can legalize these photocopies for a nominal fee.
Photography: Taking photographs of the Presidential Palace, airport, and military or other government buildings is strictly forbidden.
Official Corruption: Official corruption is reportedly common, but paying bribes is strongly discouraged and may make you a target for further attempts at securing bribery payments.
Currency: Gabon is largely a cash economy. Credit cards are accepted at only a few major hotels, and because of the high rate of credit card fraud, you should exercise caution when using them. Travelers’ checks can be cashed or dollars exchanged for Central African Francs (CFA) at hotels and banks. ATMs are available in major urban centers, and dispense CFA. You should exercise the same safety precautions as in the United States while withdrawing funds from ATMs as they are commonly targeted by thieves.
