What visa options are available for holders of Israeli or Portuguese passports looking to stay in Thailand for 6 to 12 months?

@Goldin ****

with the multi entry tourist visa you have to follow the same rules as with a regular tourist visa (ie you get 60 days that can be extended another 30 days once. At that point you have to exit the country and re-enter, which you can do on the same visa (hence the multi entry bit). The visa itself is valid 6 months from date of issue. If you exit and then re-enter on its final day you then get 60 days which can again be extended for another 30, giving you a theoretical total of 270 days with 2 exits and re-entries. In practice it will likely be just under that as you're unlikely to enter the country on the day your visa has been approved
