This is the situation, Adsense sends money to my sister and to her address in the Philippines, Now, my sister is currently in the States. Can she get the money in a US Western Union Branch and fills up in the receive form her Philippine address??
From their help pages: " Will the receiver be able to pick up the money at any Western Union location? The Receiver can pick up money at any Agent location in the city and country you specified when sending. " So it seems the answer to your question is NO.
