Is it allowed to pray Ghaibana Janaazah salah? (Some one who is dead in another country?)
Answer:
In the name of Allah, the most Beneficent, the most Merciful.
According to Imam Abu Hanifa [ranhimahu] and Imam Malik 
Janazah Salah over someone whose body is not in front of him i.e. in another city or country is impermissible. In the Hanafi Fiqh, the body of the dead person must be present in order for the Janazah Salah to be valid.
Besides a couple of incidents, most notably the Janazah prayer of Najashi whose body was not in Madinah, the Prophet of Allah 
did not pray the Janazah Salah of anyone who may have passed away or been killed somewhere else besides Madinah. (Dars Tirmizi p.299 v.3)
