Lifewide learning encompasses all forms of learning and personal development in formal, non-formal and informal modalities. This article discusses the relationship between Lifewide Learning, Social Network Sites (SNSs) and Migration by reflecting on the role of SNSs as a resource for informal learning in the context of migration and its impact on the postdigital field of action. This article argues that SNSs are fields of action that are ubiquitously used and are deeply interwoven in everyday life, especially for people who wish to/or have already relocated. In these fields of action, interaction, emotional support and constant learning take place, impacting the lives and experiences of people undergoing migration. Therefore, this article considers that SNSs are highly relevant resources for learning 'informally', where sharing personal experiences not only provides concrete information regarding a situation but perhaps, more importantly, people who share or seek information find companionship in the realization that they are not alone with their doubts or situations in their new location.
