The advantages that multilinguals exhibit over monolinguals are not only restricted to linguistic knowledge but they also extend outside the area of language.
The substantial long-lived cognitive, social, personal, academic and professional benefits of enrichment bilingual contexts have been well-documented.
Multilinguals can expand their personal horizons and, being simultaneously insiders and outsiders, see their own culture from a new perspective not available to monoglots. As the learning of a new language usually brings along a revelation of a new culture, languages’ learners can better understand people of other countries, thereby lessening racism, xenophobia and intolerance.
Multilinguals are not restricted to a single worldview but have a better awareness that other outlooks are possible, enabling them to be more flexible in their thinking. This also allows them to be better problem solvers for gaining multiple perspectives on issues at hand and improving critical thinking abilities.
In the work environment, employees' ability to speak several languages offers them the chance to communicate with people they would otherwise not be able to interact with. A high language proficiency also increases job opportunities in many career fields.
Here is an infographic that shows in a very simple and practical but integral way all the advantages of being multilingual.
