, the problem is that the paper she got is not the 100% the same they have in the archive in BKK.
The Thai ID number she has belongs to a some other guy in Thailand... There is hundreds of Thai adopted people that have the same problems now because of the corrupted lawyer who was behind the adoptions in 1976 to 1979 :(
But her baby Thai passport is not enough proof/evidence to get her old citizenship back again :( We know because we have tried to fix this for some years now :/
