Greetings from USA… Doing a SEA trip hopefully by end of March and having some visa questions… Plan is to do the PI for 28 days then to Thailand on the 30 day visa and get 30 day extension. Then want to head into Laos / Cambodia for several weeks or a month then back into Thailand for another 30 + 30… Is this allowed? Because I am trying to remain fluid with my schedule not really wanting to do the tourist visa. Legitimate educated advice please…
