Popped into Jomtien Immigration today to get a residency letter for my D/L renewal. In and out in 20 minutes. Back an hour later to get the paper. Had to go make 1 copy, only 1 person ahead of me.
Place was busier than I expected. I strongly recommend those w visa status issues NOT wait til the end of Sept to sort them out.
Did notice they have online que available now. As we get closer to the end of amnesty it might save you some time.
