A few places have begun to charge international students additional fees besides tuition: at Purdue University, it was $1,000 this year and will double next year; engineering undergraduates at the University of Illinois at Urbana-Champaign had to pay a $2,500 surcharge this year.

“We’re in something akin to the gold rush, a frontier-style environment where colleges and universities, like prospectors in the 1800s, realize that there is gold out there,” said David Hawkins, the director of public policy at the National Association for College Admission Counseling. “While it’s the admissions offices butting up against the issues most right now, every department after them, every faculty member who comes into contact with international students, is going to have to recalibrate as institutions become more international. I see a cascading list of challenges.”

They have already begun here at Washington’s flagship university, where orientation leaders last fall had to explain, repeatedly, the rigorous campus recycling practices, reinforce no-smoking rules and, at the make-your-own-sundae bar, help people get the hang of the whipped-cream cans.

But there are deeper issues, like how much latitude professors should give in written assignments.

“We recognize that people from other countries often speak with an accent,” said John Webster, director of writing at the university’s College of Arts and Science. “If we’re truly going to be a global university, which I think is a terrific thing, we have to recognize that they may write with an accent as well.”

For example, because Mandarin has one pronunciation for “he,” “she” and “it” and nothing like “a” or “the,” many Chinese speakers struggle with pronouns and articles. And English verb forms, like past participles, gerunds and infinitives, can be difficult to master, since Chinese verbs are unchanging.

Given that Chinese students’ writing will be “accented” for years, Mr. Webster believes that professors should focus less on trying to make their English technically correct and more on making their essays understandable and interesting. But he knows this could be a controversial issue, reminiscent of the Ebonics debate decades ago.
