Students should be required to demonstrate proficiency in a foreign language, such as English, before graduating for several reasons:
1) Learning English provides opportunities for greater global competitiveness through access to knowledge, understanding of other cultures, and professional development.
2) English is a lingua franca that facilitates international and professional communication, improving opportunities for employment both within and outside of Colombia.
3) Speaking multiple languages has mental health benefits like increased brain plasticity, concentration, and delayed onset of diseases like Alzheimer's.
