Professional Service, Inc. (PSI) was incorporated in 1996. PSI specializes in providing insurance services to the international student and visitor market.

In 1996, PSI started to market and sell medical insurance to international students and scholars on the Internet. The new technology enables PSI to provide better service, cover a larger market, and lower the costs. The significant savings are passed directly to PSI customers.

In 1997, PSI developed the International Visitor Medical Emergency Insurance. The new plan helps international students to purchase medical insurance for their visiting parents and friends at a reasonable price. This plan is also warmly welcomed by other international visitors.

In 1999, PSI set up a technical support group. This new expansion has enabled PSI to constantly upgrade the service system and website, creating better service for PSI customers. (From 2004, the IT group has expanded to also provide technical support to www.yomovo.com and www.sanyavacation.com)

In 2002, PSI launched the Graduated International Student Medical Insurance Plan. This plan serves the customers who are no longer eligible for a student plan and not yet covered by an employer sponsored plan.

All these efforts and innovations have made PSI one of the most popular insurance providers among international students and visitors. PSI customers can count on PSI to continuously lead the market with its business and technological innovations, outstanding service, and reasonable premiums.
