I have the LTR based on remote working and it was easier than I thought make sure you tax returns are in order. and if they are in a foreign language other than english or Thai make sure they are translated by a registered translator and stamped. Also the process can drag on so call them frequently to see if they have everything and push them along. Remember the LTR costs only 50k baht and there is no 90 day reporting only yearly. So the LTR is far superior to the elite
