I wrote a different birthplace on my Ds-160 application

And i already sent it. Would it affect my visa application? Is there a possibility that I could change it? And can i just show my birthcertificate if ever the consul would ask?

Ask your rmployer if you can re-schedule the interview and fill out new DS-160

Which visa are you going for?
