Verify whether you had country of citizenship and country of issue as the two options, or whether you had a ‘place/city of issue’ as well. Because selecting US city makes sense only in the latter case. If you only had country of citizenship and country of citizenship as the two options then it should’ve been India.
I don’t think this is that big of an issue but you should contact them and advise them that you may have selected the wrong country and request that they make that change in your application. If they make the change or ignore it atleast it won’t be like you made a blunder in your application and they cancel it because of wrong information.
