I don't see any practical utility to this article. Visas are very country-specific, and some of the info (eg. Saudi supposedly not needing transit visas) is outright incorrect. Jpatokal 01:37, 4 June 2008 (EDT)
The banner at page-end indicates this is just an outline...but no date for that entry. Believe page has developed past that point, e.g., explains why you may need one or more, and consequences of not having such. Don't feel authorized to remove banner.
Definitely agree it should receive frequent fact-checking (an error could cause considerable grief), plus ".gov" or other clean links to dependable sites indicating which nationals need/don't need visas for which types of entry in which countries, e.g.,  for U.S. travelers.
