Spelling mistake of mother's name in my passport - Visitor Visa Help needed.

[KH1982]

Friends, 

Please help me sharing your experiences.  I'm planing to apply for visitor visa (USA) for my mother . Her name on MY passport and MY birth certificate had few letters difference but name sounds same. 

 

Do i need to change my passport and birth certificate as per my mother's name in her passport? else is that okay if I apply visitor visa ? Appreciate for your experiences.

 

Thanks

Kh
