Introduction. International communication requires all those interactions between states, companies, institutions, and people, on the other hand, globalization has integrated the media, especially the Internet. Learning a new language is a fundamental requirement to work as an international communicator. Therefore, working in international settings, or in a place where people have a different vision and culture, implies knowledge and respect for others. The article is dedicated to the analysis of the use of English as a language of international communication. This problem is especially important because globalization is impossible without the presence of a language in which all people on the planet can communicate. Objective. Reviewing English are its linguistic characteristics, revealing the economic and educational context in the countries that make up Latin America as an international language. Methodology. The field of science and higher education constitutes a strategic space where the problems of the globalization of English as the only hyper-central language are clearly reflected: From a restricted multilingual model of a few languages, German, French and English that expressed the scientific field a century ago, we have moved towards an almost absolute predominance of English. Results. From a Latin American perspective, three compelling reasons stand out that should drive us to use various foreign languages. This text will analyze the biased nature of studies on the distribution of languages ​​in indexed publications when they are taken as representative of the scientific field. Conclusions: One of the characteristics of modern English is its variability. Well, this does not have a single standard, and those who are going to learn this language must decide for themselves which of its variants they will learn: British, American, Australian, Canadian, etc. An alternative to achieve a complete proficiency in the English language is to conceive the space of sciences and higher education, structured as a sociological and communicational field that integrates the spheres of production, circulation, and training. English has official or semi-official language status in sixty-two countries around the world and is considered the language of international communication by 97% of the world's population.
