To be frank with you, there is no axiom in Astrology to find out whether you will settle abroad since the word abroad is a man made term and God does not endorse it. Division of this world into countries is done for administrative convenience and each country is not a separate entity, but a part of the whole World. And you also belong to this world not to any specific country only. All the people in the world use the common resources like air, water and other materials available. There is no foreign air, foreign water etc.
