I am looking to relocate to thai early next year. Atm if I can prove monthly income of $3000 a month though I may have the 500,000 thb saved up before then but if I don't before I need to leave is the $3000 monthly sufficient ? to get a DTV VISA ? And I researched it's validity is 6 months at a time. Is visa runs legal ? Let's say I go to Vietnam for a few days and return to restart a new entry ??? Please advice
