I think you can`t unlink both factors (genes/womb and country) because genetic defects and growth of embryo are partly affected by social and environmental circumstances of the country, carciogenic pollution and food, malnutrition or physical stress of the mother (hard work, etc.). Thatswhy I would suggest, that maximum live expectancy is independant from origin (see Nesse, Williamson: Why We Get Sick : The New Science of Darwinian Medicine)but average life expectancy is primary dependent on country of origin.

Some immigrants live like the country of origin and presumably they would have life expectancies similar to said country. Some immigrants live like the host country and should have similar life expectancies. 2 caveats 1- genes matter 2- what happens in the womb is enormously important and must be taken into consideration.
