^ Going to pakistan may be different but what about other countries? Us, canada, europe, austrailia etc? I think parents know if their daughter is mature and capable enough to handle living alone, else they wouldn't be sending her to begin with...at least that's what i thnk.
Cant really say.. Its like a guy going there.. she can be still in touch with the relatives and stuff.
But a boy or girl living away from parents would have more options.
To me a girl should not sent out at her own...simple... unless she is true genius... trying to come up new energy source for the world...or some thing... and research can be done in pak..
