Indeed you are allowed to send it outside your home country if there is a greater need for it outside.  I would say this would be the case in North America and the West and even some of other developed countries where people regularly consume meat, while the people like refugees or war torn countries or even the so called third world countries crave for meat and they often look forward to the sacrifice.

 

Having said this, we must rush to add: we should never forget the needy and destitute in our home country for not everyone can afford to buy meat. Many are on welfare, or unemployed or students who crave meat, and hence would benefit from the sacrifice.

 

Therefore, we ought to balance the two: so while some people offer sacrifice at home others can make arrangements for sacrifice overseas where there is a greater need.

 

Almighty Allah knows best.
