Some universities are making an extra effort to welcome international students to the United States with the help of Port Columbus. Ohio State University and Ohio University in Athens are greeting new international students arriving in Ohio through welcome areas provided at the Columbus airport. The schools also offer free shuttle rides from the airport to the universities. Ohio State began its new welcome effort last week and will continue through Aug. 20. Ohio University says it has provided the airport welcome service since 2008 and offers it again this week.
