The number of newly arriving international students declined an average 7 percent in fall 2017, with 45 percent of campuses reporting drops in new international enrollment, according to a survey of nearly 500 campuses across the country by the Institute of International Education.

根据美国国际教育协会对全美近500所高校的一项调查显示，2017年秋季新入学的国际学生数量减少了7%，有45%的高校报告称新入学的国际学生数量出现下降。

Experts cited an uncertain social and political climate in the United States as part of the reason for the decline in enrollment.

专家提出，美国社会和政治环境的不确定性，是入学人数下降的原因之一。

"It's a mix of factors," said Rajika Bhandari, head of research for the institute. "Concerns around the travel ban had a lot to do with concerns around personal safety based on a few incidents involving international students, and a generalized concern about whether they're safe."

该协会的研究负责人拉吉卡·班达里表示：“这是多种因素的结合。由于发生了几起涉及国际学生的事件，人们对旅行禁令的担忧很大程度上是对人身安全的担忧，也有对自己是否安全的一种普遍担忧。”

Another reason for the decline is increasing competition from countries like Canada, Britain and Australia, said Allan E. Goodman, president of the institute.

协会主席艾伦.E.古德曼称，该数据下滑的另一个原因，是来自加拿大、英国、澳大利亚的竞争在不断加强。

The drop in new students signals potential financial difficulties for some small universities that have come to rely on money from foreign students, who provide an infusion¹ of $39 billion into the United States economy each year.

新入学学生的下降，预示着一些依靠外国学生、规模不大的高校有可能出现财政困难。外国学生每年可以为美国经济贡献390亿美元。

Particularly hard hit are campuses in the Midwest, according to the institute.

据该机构透露，中西部的高校受到的打击尤其严重。

At the University of Iowa, overall international enrollment this fall was 3,564, down from 4,100 in 2015.

今年秋季，艾奥瓦大学的国际学生入学总数从2015年的4100人下降到了3564人。

Downing Thomas, the university's dean of international programs, said that some other schools in the Big Ten are also experiencing declines, and none are seeing the rapid increases of the recent past.

艾奥瓦大学国际项目主任唐宁·托马斯表示，十大联盟中的其他高校也遭遇了人数下降，没有一所学校还有不久前的那种快速增长。

While Iowa primarily lost Chinese students, the University of Central Missouri experienced a sharp decline this year in students from India, said Mike Godard, vice² provost for enrollment management.

艾奥瓦大学减少的主要是中国学生，而中密苏里大学负责招生工作的副教务长麦克·戈达德则表示，该校今年的印度学生数量骤降。

In the fall of 2016, the Warrensburg, Mo., university had 2,638 international students. This fall it has 944.

2016年秋季，中密苏里大学共有2638名国际学生。而今年秋季只有944名。
