In the course of the research, the effects of foreign guest work, both in the narrower and broader sense, in Csíkszentkirály and its surroundings are investigated. The subject is very topical and of great importance today, but despite this, little information is available. This phenomenon has grown into a rapidly developing and important industry with a very significant impact on the population, which is why we believe it is important to record, monitor and analyse data on it. The reasons for going abroad are mostly economic, with the main objective being to earn as much income as possible. However, we suspect (and this is confirmed in the paper) that labour migration abroad has a significant and often surprising economic, emotional and social impact on the daily life of an individual, a family or a community. This impact may be direct or even indirect, but it affects the financial, emotional, social and community situation of an individual or community. It was also essential to examine whether working abroad is, in fact, essential to achieving a decent standard of living. After examining the results, it seems that, although not easy and much more challenging, working at home can help achieve these goals, but going abroad offers a much simpler, shorter and more spectacular result.
