On the other side of that coin: imagine you are a doctor but don't want to stick around. After a horrible break up with your girlfriend, you have decided you would like to get out of the country. You go to the international recruitment agencies with your credentials and your resume and tell them to send you wherever they need you most. They do some checking and soon you are packing your heartache and your little medical bag and off you go to Asia or to Europe or to South America.
The international language recruitment agencies do not focus purely on the medical field, of course, but that is one of the major areas where they need to bring people in from other countries. There are other needs that have to be met though, including in the human resources, social service and the retail industries. An employer in Europe might decide that they need someone from the United States to come in and handle some of their retail duties, especially if they are trying to sell products to the States. They can post the job internationally but may not get the response that they need or want. Their next step then is to look for their new employee by turning to the international recruitment agencies who will give them a listing of their best in the field. If none of the candidates turn out to be what the company really needs, then the agency will start recruiting new people once again.
As a potential new employee, being called by an international recruitment agency can be both a positive and a negative. For instance, you might be hoping that you are going to be asked to do a job in a certain country but are really needed somewhere that was not your first choice at all. Each of the international language recruitment agencies have a different policy about how many jobs you can turn down, so always learn all of the guidelines so that you don't hurt your chances of getting the position that you really do want.
