:?: "What's means?" What an awful story"!!!!

                    I have some ...story happended with my daugther.
I am Thai and my husband is Vietnames. We have one daugther yes she is "Mind or Mindnguyen" she was born in Ho Chi Minh. Afterward she got two nationality and hold two passport.
    In Feb 07, I and Mind visited Thailand my hometown. Mind travel holding Thai passport, and then when she came back Ho Chi Minh Mind also hold Thai Passport. This is my case I absolutely confuse, because Mind have to do a Visa.
I wonder? why she have to do a visa due to she is Vietnames citizen.
