, do you know if I have to show proof of residency at Chaeng Wattana immigration office? I forgot to register at Samut Prakan when I came in, so I'm want to use Chaeng Wattana instead?
, he probably is. But the van leaves at 1:30 when the consulate opens. I jump in a cab to the border, get an airport van. That way you are back in bkk at 9pm.
