Error in I-485

[al1990sss]

Hi
My interview was scheduled on Jan 23rd, EB-2, NIW.
I just found out that in my employment history section of I-485 I submitted I made a mistake: one of my previous employment start date was listed as 07/01/2012 but it actually should be 07/02/2012. How bad actually is it? I am asking it because I do know that during the interview I take an oath and in principal every incorrect thing, even insignificant, is lying.

Not a big deal. Not really an issue, but if you want, you can bring a small statement. Just write the correct dates and employment history that you want to correct. Sign the bottom and that's it. You can say at the interview "there's a slight typo in my employment history with one of the dates, here are the correct dates".
