only the LTR does not require 90 day reporting but reporting 1 year. So if you fly out of Thailand more frequently than once a year you will never need to report with an LTR
simply not true. for example if a person has an employer in Japan, they have a japanese work contract, there money is paid into a japanese account, and the work they are doing is for a facility or client in Japan then this is a non issue. The lawyers of my japanese partner company checked this. yes I meant MOL but so used to MOM.
