Hey!! I’m planning a trip to Thailand on my RTD as well. Can you let me know how long it took you to get the visa and whether the process was okay? Also, what airline did you fly with and was there a transit visa you had to get?
I sent mine on 7th April to the same address and it went in their system on the 16th. I’ve gotten mine but my moms is still processing even though we sent it in one package.
