The duration of stay allowed on an Irish visa depends on the type of visa you hold and the purpose of your visit. Common visa types include tourist visas, business visas, study visas, and work visas. Each visa type has specific rules regarding the maximum length of stay. For example, a tourist visa may allow a stay of up to 90 days, while a study visa can permit you to stay for the duration of your course.
