Visa & passport
Your passport must be valid for at least 6 months beyond your date of entry. You can obtain your visa upon arrival at the airport or border crossings. Prepare a valid passport, a passport-sized photo, and $35 USD in cash. You will receive a tourist visa valid for one month after a few minutes of waiting without prior formalities. If you don't have a photo with you, don’t worry—you can have one taken there for $1 USD.
