Most nationalities can obtain tourist visas to Jordan upon arrival at any entry point, except at the King Hussein Bridge, which requires a pre-issued visa. A single entry visa will cost JD20 or approximately US$30. Single entry visas are officially valid for one month from the date of entry, but you must register them at a main police station within one month of your arrival. ASEZA has recently introduced a special Economic Zone visa for Aqaba, known as "ASEZ visa" for anyone just visiting Aqaba. Anybody arriving in Aqaba, whether at the port, the airport or any border crossing can get a free visa. There is no obligation associated with this visa, providing you leave the country within 15 days. You do not need to register the visa for renewal. Everybody without a specific exemption must pay the JD8 departure tax whenever they leave the country, whether they hold an ASEZ visa or not. Travelers staying less than 24 hours are considered to be "in transit" and are exempt from departure tax, as are certain cruise ship passengers.
