The rapid expansion of Internet users has given Web-based surveys the potential to become a powerful tool in survey research. As an application of this technique for gathering data, the International Student Survey was designed to explore factors that might influence choices of college majors and the social support network system among international students at Arizona State University. Cover letters with the links to a Web-based questionnaire were sent through e-mail to the entire international students population. Given that no incentive was offered, this study received a total of 929 completed surveys for an overall response rate of 22% after three waves of solicitations. This article discusses the methodological concerns and problems that arise from using Web surveys, including noncoverage, nonresponse errors, confidentiality concerns, and technical problems. Suggestions for improving response rates also are discussed.
