A practical worldwide guide to electronic visa categories, purpose-based routes and the difference between an eVisa, ETA, visa on arrival and regular visa.
Countries do not use one universal eVisa catalogue. Each immigration authority decides which purposes can be handled online, which nationalities are eligible and whether the result is a full electronic visa, a travel authorisation or an application that still needs a consular step.
The most common worldwide categories are tourist, business, medical, student, transit, family or visit, work or employment, investment, conference or event, religious travel, seafarer or crew and miscellaneous or special-purpose routes. A country may combine several purposes or publish separate subcategories.
The safest way to choose is to start with the real purpose of travel, then check the passport rule, entry count, permitted activities, stay length, evidence and the official application channel.
An eVisa is generally an electronically issued visa. An ETA is a digital permission to travel for eligible visa-exempt visitors, while visa-on-arrival permission is assessed at or before arrival under destination rules.
Start with the real purpose of travel. A tourist, business, student, medical or transit route may have different documents and permitted activities.
Do not choose a category because it sounds convenient. Choose the route that reflects the actual activity and then verify that your passport and destination are eligible.
The labels below appear across different national systems, but not in the same combination everywhere:

Tourist and business eVisas are common, while medical, student, transit, family, conference, religious, investment, work and special-purpose categories exist in some national systems.
An eVisa is generally a visa issued electronically, but the legal meaning and conditions depend on the issuing country. Read the destination’s official definition.
An eVisa is an electronically issued visa. An ETA is usually a digital permission to travel for eligible visitors who may not need a visa; it does not necessarily grant entry.
Normally no. Work and formal study usually require specific permission, even when the application is online.
Start with the true purpose of travel, then check passport eligibility, stay, entries, documents and official instructions for the destination.
