I did my VISA through a service Mile High Visa in Colorado back in September 2018. I forgot to put City/State for all my addresses and they just wrote it out on my app. There were no issues with my visa except for they wanted pictures of my parent's passport and my birth certificate. When I was taking a picture of my birth certificate, I realized I put the wrong birth city on my original application but I didn't get any additional request after that and I was shipped back my passport along with my 10 year visitor VISA.
