In the article suggested to the reader's attention an attempt is made to look on the international migration from the position of developing countries. The article consists of three parts, each one containing statistical material. The general state of modern migratory processes, their difference from their prototype of the epoch of formation and consolidation of the world economy, the scale, the dynamism and geography are considered in the first part. The second part characterizes the place and role of seasonal work in housekeeping, the latter being the basic link and a system-forming pivot in international migration. In the last part the main attention is focused on the migrants' money orders and the problem of a balance in the positive and negative effect of international migration for the developing economic systems.
