I would say some can be lucky like me who travelled back to Thailand while dtv is still pending..so now that it's issued, I just need to fly out and reenter to activate it. In my opinion as long as the last status is pending approval it is almost certain as opposed to pending doc review, then waiting is the key Bec they might really ask for more docs so better to stay put..
I was in Vietnam and applied from there..I guess youissed the thread..I am full aware of the process..due to expiring visa in Vietnam I had to come.to.thailand..so now that it arrived I just need to fly out and reenter to activate it..sorry if I confused you..
