I don't think so. I've searched multiple stories, some posted here, for information on how he receives donations from "Catholic and Buddhist organizations" or otherwise, and found no information at all. I am not even sure if the Catholic organizations are in Vietnam or elsewhere.
I found one reference to a girl sending a donation directly via her parents who hand-delivered it to him, but that is an obvious stretch for probably all of us. Short of contacting the reporters from the various stories who have met him, it may be that the publicity from these recent stories (one made the L.A. Times), may drum up a "grassroots donation train" that would reach him and not be stolen by corrupt officials along the way, as is a fear I had when considering whether I could contact the Vietnamese embassy about him & his orphanage.
Oh my goodness. If you should find an address for donations, PLEASE let me know!!!
Could either of you please freepmail me if you find a way to donate to this most worthy cause?
