you are misunderstanding. Visa run means going to another country to get a NEW visa. You are talking about border bounce. No need for a visa run as DTV is valid 5 years….
and today mine seem to be frozen as well. Almost emptied it out though due to the writing on the wall. Luckily I have Indonesian accounts and Nexo card
Generally 6 months for any visa, but if i had less than 5 years i would get new passport before getting the DTV. I had 2 years left and got a new one to avoid the hassle of moving visa to new passport
