Colombia is one of the most diverse countries in cultural and linguistic terms, with 68 indigenous languages in different regions. However, because of the bilingualism policies implemented in the country and the decision to promote the teaching of English as a foreign language from a homogenization perspective, a great majority of languages have been disappearing over time, which affects the cultural and historical legacy that these languages allow. The trends of the globalized world have provoked non-English-speaking countries into starting bilingualism plans to enter the dynamics and requirements for new professionals. However, these initiatives have been detrimental to the cultures of the countries themselves. In Colombia, the teaching and preservation of aboriginal languages have been omitted to introduce foreign languages. The national bilingualism programs launched in Colombia during the last decades are focused on linguistic homogenization, leaving aside the cultural and linguistic richness of the country, which affects the communities that have a minority language and are in danger of extinction. This is qualitative research with a descriptive documentary research methodology whose main objective was to analyze the policies of bilingualism in Colombia and their impact on preserving aboriginal languages. A review of bilingualism policies, ethno-education policies, and academic offers in higher education were reviewed from the perspective of descriptive-documental research. The research results show that bilingualism policy decisions have favored the inclusion of modern languages, leaving indigenous languages at a disadvantage. A review of the academic offerings of higher education in modern languages and ethno-education shows that the latter is very limited while the former is increasing, as well as the reduction of aboriginal languages in the country and the lack of educational opportunities and teaching training for the indigenous population.
