Mother's name issue in my passport

[jshreya42]

Hi folks,
I needed some help with my passport and documents. My mother's name in all my documents including my passport is her nickname XYZ, whereas in all her/ my father's official documents it is ABC ie her official name.

While applying for VISA to US/Canada do I need provide her name same as the one mentioned in my passport ie XYZ or do I need to mention her official name ABC?
I'm trying to get it corrected in my passport currently.

I have only one affidavit which proves that ABC & XYZ are the names of the same person. Don't have any other document for it.
Also if I don't change her name in my passport ie keep it XYZ only then will I ever be able to call her to foreign country as a dependent?
Any ideas if affidavit/gazette for name change is considered valid outside India?

Are highschool marksheet really needed anywhere ie 10th/12th marksheets?

Please let me know your thoughts.

For all her visa applications her name should be mentioned as per her passport.

An affidavit would work, mentioning both names belongs to her. You can also mention her nickname (matching in your passport) in her DS160 as "Other names used", to show the relation between you & her.

For visit visa for parents (age 60+), their high school mark sheets are not required.

Is my highschool marksheet really needed anywhere ie 10th/12th marksheets for any visa application?

No, not for her visa application. Unless you want to use those mark sheets to prove that both names belongs to her.

Is my own highschool marksheets needed anywhere I mean for my own L1/ H1B visa application?

No "required" for you, but good to have.
