Regarding visa requirements for traveling to Namibia, the necessity of a visa depends on your nationality. Visitors from several countries, including the United States, Canada, Australia, the UK, and many EU nations, do not require a visa for tourist stays of up to 90 days.  However, travelers from other countries might need to apply for a visa in advance or can obtain a visa upon arrival for tourist purposes at select entry points like Hosea Kutako International Airport and Walvis Bay International Airport. It's important to have a passport valid for at least six months beyond your date of entry into Namibia, with at least three blank pages for entry and exit stamps.  A return ticket is also required. For the most up-to-date information and to confirm whether you need a visa based on your specific nationality, it's recommended to check with the nearest Namibian embassy or the official Namibian Ministry of Home Affairs, Immigration, Safety and Security website. In addition to the visa, it's advisable for travelers to have a foreign travel insurance. This insurance can provide coverage for various unforeseen circumstances during international travel, such as medical emergencies, trip cancellations, and other potential issues that could arise while abroad.
