H1B-urgent: changing one entry in DS 160 after advance document submission

[johnnyDoey]

Hi,

In the DS 160, i entered my attorney name for "person/company who filed the petition" instead of my employer name. I realize it has to be filled with the employer name in the printout since it shows "PETITIONER: <employer-name>" in the approved 1797.

I already submitted the DS 160 confirmation page in advance document submission at the hyderabad consulate, but I'm worried if this mistake can get my visa rejected.

My employer is in the list of top 5 companies/employers in the world and the attorney name is also visible in the approved I797 form, although not under the "petitioner" field. Will this in anyway help relieve this mistake?

I've heard around that I can fill a new and accurate DS 160 (without setting up a new appointment) and take it instead to the appointment and explain the mistake to the visa officer. Is this a myth/considered gray? Is there any paperwork I need to fill before that?

Please reply as soon as possible. Thanks in advance for your help!
