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.)
I got mine in May. And I have zero regrets even if I could've milked the amnesty (which wasn't clear at that point.) The amount of anguish spared and having to deal with immigration, is already great value to me.
A little over a month seems a little tight to obtain Elite. I would apply immediately (which won't cost you anything) and start talking with them directly while waiting for approval.
