Viyu / Information sources
Information sources.
Viyu is an independent private company. We are not affiliated with any government, embassy, consulate or visa application center. Only the relevant authorities decide on applications.
Every rule in Viyu is compiled from the sources below. In the app, each rule shows a link to its source and the date it was last verified. This list is generated from the rule base: 137 sites, 1574 citations.
You always apply yourself, through the official channel. If anything differs from the official source, the official source applies; tell us via the support page.
