Visa & Passport
Unless you're an American citizen, this is one of the hardest countries in the world to get a visa to. US citizens do not require a visa, but do need the following to present when entering: two visa applications, two passport photos, bank statement noting a minimum of USD2,000 in your account, as well as proof of yellow fever and cholera vaccinations. In Washington DC, the fee for the visa is USD100.
Citizens of other countries need to submit to an Equatorial Guinean embassy all of the above, plus passport and letter of invitation. If the stars are properly aligned this might be enough to receive a visa.
