Information about Change in LAST NAME

[immihelp]

Hello,

I need to change the "Last Name" of my wife in her PASSPORT. Can you please help me with the procedures specifically on the following issues :

1) Official website where I can found the details of documents required ?

2) How much time would it in completion of the process after sending the application as I need to apply for her H1B Visa. ?

3) Does she need to be present in person ?

4) Can you please provide with a contact number where I can talk to a representative in case I need further information about the procedure ?

Thanks
