Maintain a level of distance
It is by overcoming any difficulties that your son or daughter will quickly rise to a new level of independence, so avoid the temptation to become too involved. Ultimately, this is his or her learning experience.
Also, it’s important to remember that study abroad students are not on vacation. Attending class with him or her—or taking your student out of class to sightsee—will interrupt the educational process and immersion experience. If you want to visit, it’s best to do so when the program has finished so you can travel together. And it’s not usually wise to try to obtain permission for your student to return home early; the end of the semester is the most important part of his or her academic experience.
