Migrants who seek paid employment after entering without authorization to work may be subject to deportation.
Recent studies[citation needed] from the OECD report that immigrants are playing a crucial role in the labor market: in the U.S., immigrants made up 22% of entries in the fastest growing occupations and 15% in Europe (healthcare, STEM, etc.).
Immigrants are also highly represented in the slowest growing occupations, making up approximately 28% of new entries in the U.S. and 24% in Europe.
Exceptions to this are Switzerland and Luxembourg, which have approximated a 2% net benefit in GDP due to migrants.
By the official government statistics around 780,000 people emigrated from Armenia during 1991–1998 due to war and the economic conditions.
