How does the postal service work overseas?
You can mail internationally from the post office as well as UPS, FedEx and DHL. Correspondence is taken via air, and will cost more than domestic mail. Packages can get pricey to ship, but your student will be able to receive packages in their host country. Private companies are considered safer than regular mail. Mail often takes longer to arrive, so avoid sending packages right before your student returns to the U.S., as they may not receive them in time.
