I have made an error in ds160, but haven’t yet paid the fees . can I fill a different form and then pay ,will it affect my visa process in any way. Note: I have signed and submitted the incorrect form
Yes, you can create another DS-160 form as you want, if you made mistakes. It should be fine. It will NOT affect your visa process in any way. You will have to carry the new confirmation page that is generated, it should be fine. Check out First Q of FAQs US Embassy Page
