Visit to a resident or Gabonese. You will be issued an entry authorization by the person receiving you. In this case, the host will require an entry authorization issued by the DGDI (commonly referred to as CEDOC).
To obtain entry authorization, the host must table a "request for leave to enter Gabon" (DGDI form to be scrupulously completed), with 2 colour identity photos of the visitor and a photocopy of the first two pages of the latter's passport.
The host must also provide a photocopy of his/her residence card, a handwritten mail to the DGDI and a job certificate or work approval.
The visitor must be in possession of the original of the entry authorization upon arrival at the airport (which may be complicated).
Or you have a visa at the Gabonese Embassy in your country of residence. The host sends to travellers a accommodation certificate legalized by the town hall of its place of residence.
The Embassy of Gabon will give you all the documents to provide (the list is long).
Business visa. For business trips to Gabon, you must provide a mission order of the company sending you, written in French and stamped, and a letter of invitation from the company receiving the agent, signed and stamped. Entry to Gabon is accepted, subject to the recognition of the society in Gabon.
Installation in Gabon. If you come to Gabon to work, you will have to submit an entry authorization that the company that receives you will be on site with the DGDI.
You will also need your passport (time to obtain the residence card: 1 months). The residence card is valid for 5 years for the French, but the validity varies according to nationalities.
