Surname and given names interchanged in Visa

[SDS]

Hi,

My parents got their visa (10 yr multiple entry) last month.They are planning to come here soon. My mother doesn't have a last name in her pass port.so we filled her surname as NONE. But in her visa instead of printing last name as LNU ,it was printed as FNU(First name unknown) and she has her first name in her sur name column. What should we do now? how will this affect my mother's visa? pl help.

thx,
SDS

Nothing to worry. I also have the same situation. I have entered USA and returned twice without any problem. While filling in I 94 form, against family name ask her to fill NONE and in the First (Given) name ask her to fill as given in the passport.
When I first visited USA in May 2005, I left the family name blank. The IO filled it as NONE.
Good Luck
