Where does the sunrise first?

You cannot answer this question the way it is asked. Earth is constantly turning. At the same time, it swings around the sun in a yearly orbit. The sun does not "rise" in the same spot every day, so it is not possible to say that any one country will get the first sunrise. Since the way the earth rotates makes the sun seem to come up from the eastern horizon, then areas on the eastern borders of their country will see the sunrise before areas on the western borders.
