Very often the concepts of "emigrant", "immigrant" are confused, and this is not at all surprising, since they are the same persons, depending on which side of the border they are considered from. Of course, you can call everyone "migrants", then you will not be mistaken for sure. However, "immigrant" and "emigrant" - there is a difference.
Migration is a concept
Initially, the concept of "migration" was used in the field of ornithology, but later referred to as the movement of people, which are the result of the last change of their place of residence. Migrants are people who leave their usual place of residence and go to a new one, or simply stay in constant movement.
This word comes from migrare (a Latin word). The words "emigration" and "immigration" are derived from it. The prefix ex in the first case is translated as "outside, outside". In the second case, the prefix im - "inside, in".
An emigrant is a person (or even a family) who independently decided to move. People who leave the country by force or are deported are not emigrants.
Emigration - reasons
There are masses of them:
- Poverty;
- Carrying out military operations in the territory where the person lived before leaving the homeland;
- Interfaith conflicts;
- Hunger;
- Family reunification;
- ethnic conflicts;
- Impossibility of obtaining a profession, work;
- Discrimination (national, social, religious);
- Natural as well as environmental disasters;
- Repressions of a political nature;
- Problematic in the implementation of creative, professional and other plans at home.
Between the names "migrant" and "emigrant" the difference is that the first people are called, moving from one place to another between regions of the country, that is, within its territory. Emigration involves leaving the state, that is, crossing the border of another country.
Persons who carry out short-term trips for personal or business purposes (including tourists) are not emigrants.
Re-emigration is the return of an emigrant to the place from which he left, that is, this is a return migration.
Repatriation, unlike re-emigration, is a return to your homeland, but not necessarily to your own, it can be, for example, the homeland of your ancestors.
Immigrant or emigrant
The terms "emigrant" and "immigrant" are antonyms. The first are considered to be persons who leave the country, and the second are those who come to it for permanent residence.
For example, a Russian woman wants to fulfill. She can call herself emigrants, just like her compatriots in Russia can call her. But regarding her new acquaintances from America, she is an immigrant from Russia. This means that she previously lived in another country, but now lives here. The woman, when moving, was an emigrant, then when she arrived at the final point for permanent residence, she became an immigrant from the Russian Federation.
Immigration is the movement of people from one country to another for long-term residence. 
The processes of immigration at the stage of settling the Earth played a huge role, these processes also significantly influenced the dynamics and structure of the population of many powers. The mixing of different populations as a result of migration leads to the development of new nations and nationalities.
The distinction as a whole can be summarized as "emigrate to" and "immigrate from". However, confusion is still inevitable, since each arriving citizen can, at a certain stage, be both.
