The Saudi Gazette runs an article that talks about both Saudi business visits to the US and Saudi students in the US.
Interviewing a Saudi Embassy official in Washington, the reporter learns that the number of Saudi businessmen and women traveling to the US has actually increased over the past year.
For students, the scholarship program being offered by the Saudi government is certainly being taken up. The numbers don’t quite add up, but according to “Nayel Al-Jebairan” [sic: he means Nail Al-Jubair], there are 4,000 undergraduates, 1,500 are in Masters programs, 450 earning Doctorates as well 200 in medical schools. There are 1,500 women on scholarships and they outnumber the men in the Masters programs.
The article notes that because women must travel with mehrams (i.e. approved male chaperones) the women tend to be married. I don’t know if the mahram is a requirement of the government scholarship program; other Saudi women travel and study without chaperones, but with permission to do so from their fathers, uncles, or brothers.
