The paper gives an overview of the general approaches and opinions that emerged during the discussion of the cross-border migration issues at the annual Forum of Altai School of Political Studies which took place on September 25–27 in Barnaul. The theme of the discussion was designated as follows: “Cross-border migrants and the host society: mutual perception and the problems of intercultural exchange”. In the “full-time” discussion that followed the online conference the researchers from Armavir, Barnaul, Kiev, Lviv, Makhachkala, Moscow, Orenburg, Petrozavodsk, St. Petersburg Tomsk, Vladivostok and Yekaterinburg participated. Choice of this conference theme was related to the urgency of that issue, not only at the national but also the regional level. Russian Altai is the region with cross-border contacts with Kazakhstan, China and Mongolia and one of the historical points of intersection of different civilizations and religions. Through its boundary move a significant part of the migrant flow from Central Asia.
