English is widely spoken in Iceland, and many jobs especially in IT, tourism, hospitality, and multinational companies do not require Icelandic. For professional roles like engineering, tech, healthcare, and finance, English is usually sufficient for daily work. However, learning basic Icelandic can improve your chances, especially for long-term career growth or roles involving customer interaction. For healthcare and teaching jobs, Icelandic may be required. Overall, strong English skills are enough to start working in most industries.
