Astrology cannot be used to find out when you will go out of India. All that it can do is give you indications of long distance travels in life. Since you were born in Sharjah you had already a long distance travel to India. And many such fruitless travels will be there in future too. Your Mars has a near zero residential strength. Do read my blog navagrahastro.blogspot.in to get a better insight into astrology and its usefulness in life.
Motherland is the that part of the Earth where you are born. Passport is not applicable to Astrology since it is man made and not accepted by Vedic astrology. That is why the word foreign is irrelvant to astrology. We all belong to Mother Earth and only long distance travels makes sense as appropriate to the times. In the olden days, crossing a river was long distance travel and the definition has changed in modern times. In other words, your question cannot be answered using Astrology.
