Mother's surname/Last name different in my passport and her passport

[chubbysavs]

Hi,
I am planning to sponsor Visitor's visa (B2) for my parents this year. I am a Permanent Resident in the USA. My mother's surname/last name is same as my dad's last name in my passport, however, in my mothers passport, she has her maiden last name (not my dad's last name) as per her certificates and other legal documents.
I have sent the required sponsor documents which also includes my passport copy. I wanted to know if there will be any problem with the mismatching last names? Have anyone of you come across such situation? Let me know

Thanks
Savs

She can carry her marriage certificate to explain the difference in last names.
