Change new DS-160 barcode number after appointment confirmation

[kanoy83]

Hi guys,

i have paid the fee for MRV and scheduled an appointment for interview. however, i used my old DS-160 barcode number to register for my appointment. i want to use my new DS-160 and bring it to the interview.

Is it ok to bring the new DS-160? or do i really need to change my appointment with the new DS-160? and how?

Looking for solutions or answers.

Thank you
