Please be sure to invite the students as soon as possible, since they are looking forward to the experience of a welcoming American home. Make sure they have your telephone number and address, just in case they need to get in touch with you about any last minute changes. It's helpful to give indication of how long the visit will be. Some international students may feel uncomfortable if they don't know how long is polite to stay.
International students miss their families.
Most love children, and will be happy to share with you about their family life and country. If you have a world atlas handy, they can point out just where they live. The students will be interested in getting to know the city better. Although they may have been part of one of InterVarsity's programs, or even have lived here for a couple of years, there may be things they would love seeing, such as botanical gardens, an arboretum, zoo, or take a tour of the Capitol Building. If they offer to help set the table or help clear and wash up, let them join you.
