Weak ties, particularly those to potential employers, play a more important
role than strong ties in the immigration of professionals to the United St
ates. I operationalize network strength through the class of admission vari
able in the Immigration and Naturalization Service's public use data files,
Immigrants Admitted to the United States, 1972-1992. I also examine the di
fferential impact of legislative measures on the availability of strong ver
sus weak ties for four groups of professionals: physicians, nurses, enginee
rs and scientists. Not only do weak ties figure heavily on the immigration
experiences of professionals, but those impacts affect women differently th
an men. Professional women rely more heavily on strong ties than on weak ti
es when compared with males in their respective professions, with the excep
tion of nursing. These findings suggests a need for further study into the
migration experiences of professionals as well as more research into how ge
ndered networks develop among immigrant professionals and how those network
s influence (either positively or negatively) immigrant adaptation to Unite
d States' society.
