Does change in name due to divorce require re-applying for tourist visa

[cipher20]

A friend of mine wants to apply for a US tourist visa (she is located in India). She is going to be filing for divorce and it may take some time for the court proceedings to complete. Her current passport has her husband's last name and she will change it to her maiden last name after the divorce. She will get a new physical passport I believe when she applies for name change after divorce. I wanted to know, incase she is granted a tourist visa before the divorce, will she have to apply for a new visa after she gets a new passport as a result of this, even if her current tourist visa is still valid. Or can she continue to carry both passports to travel to US when she wants.
