Need help on adding spouse name in USA embassy

Hi All,

I need help on getting passport for my kid, who is in India and add my wife’s name in my passport, who is currently in India.

Currently, I am in Washington DC area and my passport does not have her name in my passport. Now, I m looking for procedures to add my wife’s name added in Indian embassy and affidavit for applying for Kids passport.

Appreciate any help.

Thank you,
