Gave client name instead of employer name as previous employer in I-129.

Hi,

When asked to submit resume for H1B petition, I submitted a resume with my client name instead of employer name. I was on OPT then. Also my designation was what I did at client's place not what my employer hired me. In DS-160 petition though I gave my employer's correct name. I am on FTE now. I have my visa interview in November. Will the VO ask me why my previous employer on DS-160 is different from that on I-129? If so what can I do for that?

Even if they ask, it should not be a big issue. You can mention that it was an error and show documents (like experience letter) to show what is really true.
