Language requirements in Belgium depend on the job and region. Belgium has three languages—Dutch, French, and German. However, many multinational companies and IT firms use English as their main working language. For technical jobs like software development, engineering, and IT support, English is often enough. Healthcare roles may require Dutch or French depending on the location. Learning a local language is helpful for daily life, integration, and better job opportunities, but it is not always mandatory for English-speaking professionals, especially in tech and global companies.
