Saudi Arabia’s visa system has become faster, more digital, and more structured in recent years. However, with these improvements has come a stronger focus on documentation accuracy and compliance. One of the most common reasons Saudi visa applications from the UK are delayed—or returned—is incomplete document legalisation or missing Arabic translation. For UK professionals, businesses, and corporate travellers, this requirement often raises questions. Why is legalisation necessary? Why isn’t an English document sufficient? And why does translation still matter after apostille? The short answer: Saudi authorities must be able to verify and understand every document submitted. This guide explains how that works—and how UK applicants can avoid unnecessary delays.
