The mobility experience leaves deep impressions on the emotional realms of those who depart from their place of birth. Among many things, identities referential are transformed and practical references of everyday life are modified. In this article, the author shows how the experience of mobility – specially, emigration to the United States – also involves Mexicans´ religious practices and beliefs for those who emigrate. This impact is reflected, among other aspects, in the transnational traditional religious practices, in certain conversion processes, and the influence of ethnic groups in religious diversity representation.
