with trans frontier parks (Botswana, Lesotho, Mozambique, Namibia, South Africa, and Zimbabwe) and some other SADC countries (Angola and Swaziland). As of 2017, universal visa is implemented by Zambia and Zimbabwe. Nationals of 65 countries and territories are eligible for visa on arrival that is valid for both countries. This visa is branded KAZA Uni-visa programme after Kavango–Zambezi Transfrontier Conservation Area (KAZA). It is expected that other SADC countries will join the program in the future. Previous common visa schemes These schemes no longer operate. The CARICOM Visa was introduced in late 2006 and allowed visitors to travel between 10 CARICOM member states (Antigua & Barbuda, Barbados, Dominica, Grenada, Guyana, Jamaica, St. Kitts & Nevis, St. Lucia, St. Vincent & the Grenadines, and Trinidad and Tobago). These ten member countries had agreed to form a "Single Domestic Space" in which travellers would only have their passport stamped and have to submit completed, standardized entry and departure forms at the first port and country of entry. The CARICOM Visa was applicable to the nationals of all countries except CARICOM member states (other than Haiti) and associate member states, Canada, France, Germany, Ireland, Italy, Japan, the Netherlands, South Africa, the United Kingdom, the United States of America, and the overseas countries, territories, or departments of these countries. The CARICOM Visa could be obtained from the Embassies/Consulates of Barbados, Jamaica, and Trinidad & Tobago and in countries that have no CARICOM representatives, the applications forms could be obtained from the embassies and consulates of the United Kingdom. The common visa was only intended for the duration of the 2007 Cricket World Cup and was discontinued on May 15, 2007. Discussions are ongoing into instituting a revised CARICOM visa on a permanent basis in the future. A predecessor of the Schengen common visa was the Benelux visa. Visas issued by Belgium, Netherlands, and Luxembourg were valid for all the three countries. Exit visas Exit visas may be required to leave some countries. Many countries limit the ability of individuals to leave in certain circumstances, such as those with outstanding legal proceedings or large government debts. Despite this, the term exit visa is generally limited to countries that systematically restrict departure, where the right to leave is not automatic. Imposing a systematic requirement for exit permission may be seen to violate the right to freedom of movement, which is found in the UDHR and forms
