To "come over" often means "to visit", in US English, is that what you think he means? e.g. I hope he comes to Germany to visit me?
You can also use "come over" to mean "travel from another place or country", e.g. many Polish people have come over to Britain in the last five years; my uncle came over from Birmingham last week. Many British people will use "come up" or "come down" if the journey is approximately "up" or "down" on the map, and "come over" if it is more or less horizontal.
