Sommario/riassunto |
|
Utilizing quantitative and qualitative research methods Bagchi examines the role that networks play in the immigration of professionals to the United States. Past research of so-called "migrant networks" emphasized the role of close interpersonal ties and focused on lower-skilled immigrants. This research shows that casual ties play a significant role in bringing highly-skilled immigrants to the U.S., but also that the importance of the "strength of ties" varies considerably by gender and occupation. Bagchi used two quantitative data sources: the |
