Migration policy was recognised as a relevant topic a decade ago, when it was acknowledged as a tool to improve demographical and economic situation of the countries. Nowadays migration issues is one of the mostly discussed theme in the European Union. Through the incessant emigration, ageing of the citizens and brain drain phenomenon Lithuania inevitably face growing demand of imigrants from third –countries. Although it is recognized in Lithuania that economic and demographic situation of the country can be improved by means of imigration from third – countries, migration policy in regard to the third-country-nationals is not ideal and it‘s practical implementation does not operate well. Lithuania does not have enough practise in this scope – migration policy in our country has been relevant only since Lithuania became the member of European Union and national migration policy was started to harmonise with requirements of the European Union. According to the results of analysis can be concluded that in order to improve implementation of migration policy in Lithuania, firstly it must be tought about purposeful and consecutive development of migration policy and integration of third-country nationals. Unfortunately migration policy in Lithuania at the moment is based only on short-term economic needs.
