I suggest you read my post again...there are 2 options mentioned....my only "argument" is that the 6 month metv is still a tourist visa and if the IO wants to they can deny entry on a metv....which if you read the other replies....does happen
Everybody's situation is different.....elite visa if you have $$$ Ed visa if you have time and $$ it sucks.....I was in the same boat with multiple tourist visas but I am over 50 so I just got the non O in Laos so I don't have to sweat this mess.. .I feel for the OP
