That is a tough one indeed. He should sneak out of the country and come here by boat and celebrate Thai style. Who's gonna prosecute a 90 year old lad(?) :)
And not only that. The "official" refuge collectors sift through everything and puts recyclable items to one side. It's a rather fascinating thing to see (although, the adjacent air is not always, erm, fresh.)
I'd say talk to Thai Elite directly. When I did mine I applied through the "top google result". Didn't even realise it was an agency of some sort (worked out nicely and didn't cost anything extra.)
