"At time of appointment, the successful candidate, if not a U.S. citizen, must have authorization from the Bureau of Citizenship and Immigration Services to work in the United States."To me that pretty much means, you're on your own. And since a worker cannot get a work visa without the employer's sponsorship, it pretty much means fuck off.
And here's another from a 4 year university:
"Successful candidate must provide documentation of identity and eligibility for employment, as required by the Immigration Reform and Control Act (IRCA) of 1986."Yet another obstacle to getting a job here in academia.
