This is one of the most difficult nations in the world to get a visa unless you are an American citizen. Citizens of the United States do not need a visa, however they must bring the following items with them while entering: two visa applications, two passport photographs, a bank statement indicating a minimum balance of USD2,000 in your account, and evidence of yellow fever and cholera vaccines are all required. The visa cost in Washington, DC, is USD100.
Citizens of other countries must submit all of the following, as well as their passport and letter of invitation, to an Equatorial Guinean embassy. If the stars align just so, you may be able to get a visa.
