In Vedic Astrology, a combination of planets and houses are considered for predicting. Jupiter, Rahu/Ketu, Saturn, Venus, and Moon are the planets that are looked at in Foreign Travel Astrology. A good astrologer like Dr. Vinay Bajrangi has to check these planets, their position, location, and association with their houses in your birth chart to predict the foreign travel yoga in your birth chart. Abroad Settlement Astrology is much more than this. Rahu is considered as the most prominent planet for foreign travel.
