Stuttgart is the home of people from 170 nations who can converse in 100 different languages.
Migrants form about 40 percent of the population of the Swabian metropolis, the highest proportion among all large cities in Germany.
These numbers clearly show that Stuttgart is a city with cultural diversity and international flair.
However, the high immigration rate also means that the state capital is obliged to intensively promote the German language.
A good knowledge of German is required for successful integration.
Many companies use the services of language schools such as the renowned ISD GmbH, which specializes in foreign language training for managers and specialists.
Its courses are tailored to individuals or groups from specific branches, companies, vocational fields or specialist departments.
