Different name on current Passport VS an old valid US visa

[Prat0402 0]

 

My father is having US tourist visa stamped in his old passport.

Old passport and visa has format -:

<Surname> <First Name> <Middle Name>

e.g.- <Surname> <First Name> ABC

 

He recently renewed passport and corrected middle name which was asked by passport office (to keep it consistent with other docs like Aadhar card, Bank docs etc.)

New passport format -:

<Surname> <First Name> <Middle Name>

e.g.- <Surname> <First Name> ABCDE (DE was appended in middle name in latest passport)

 

Can he travel with his old visa while carrying both passports OR any specific documents he needs to carry OR he needs to get altogether new stamping ?

Kindly suggest.
