As you know, not only one house responsible for foreign travel. Important house for foreign travel is 9th house & 12th house and in last 7 and 8th house.
Any strong benefic connection of ascendant to 9th/12th house guarantee for foreign travel.
Most important house for foreign travel:
Most important house is 9th house. Why I am telling 9th house most important? 9th house and 12th two main house for foreign travel but 12th house also represents debs,loss etc…. If planet strong here then it will give travel but not beneficial for financial. If you travelling through your strong 9th house then obviously it will best for you. It will give immense wealth and reputation in foreign land. Another logical point need to mention here which generally your astrologer will not tell you.9th house represent Sagittarius sign in Kal-purush chart which rules by Jupiter fire element and dual sign. Jupiter is the main significator for foreign travel. So it is one of the most important houses for foreign travel and settlement.
The profitability of stay/visits in a foreign country depends on the strength of the significators involved. Rahu’s connection with houses connected with foreign journeys/residence .
For the Settlement, strong 9th and ascendant connection should be from 12th house and no connection with 4th house otherwise person will go and after sometime he will come back due to some reasons. If ascendant lord connection in 9th and 12th house in fixed sign then probability more for permanent settlement in abroad.. If the yoga has the influence of movable signs, person is likely to return. We should check the first 15 degrees in any common sign represents fixed nature and the second fifteen degrees represents movable nature.
Role of Jupiter/moon/Rahu in 9th house and 12th house:
As I already pointed out, 9th and 12th houses represent the prospects of long distance travel and life away from home respectively. Hence, when the lords of these two houses with Jupiter/moon/Rahu are in conjunction or in mutual aspect, a strong yoga for foreign travel is formed and such a person goes to a foreign country definitely.
