@Ke**
is sorted. Thanx one and all for the advice.
He's gonna go next week, cancel his work permit and his two year extension, They'll stamp him in to the 30th as that's his last day on his termination paperwork.
His family will get back on the 26th & they will go cancel their extensions once they're here, also getting stamped in until the 30th because they're "piggy-backed" on his 2 year Non-B extension.
Then they'll all go to Vientiane to snap up single entry tourist visas.
Again, thanx to everyone who offered advice. (y)
I believe we're done :)
