Belgian passport holders need a visa to visit Vietnam, which can be obtained either through the Vietnam embassy in Belgium or by applying for a visa on arrival online. The visa on arrival application requires an email address, online payment, a valid passport with at least one blank page, passport photos, and cash payment upon arrival. It allows tourists and business travelers to obtain a visa faster than through the embassy. The Vietnam embassy contact information in Belgium is provided for those applying for a visa directly through the embassy.
