This question already has an answer here:
This is for French Schengen visa appointment in San Francisco.
I read one relevant question but it states you can't change travel dates online in your application, which is what I am aware of; there's no option to do that online. The only way to do it is cancel current application and rebook appointment. But is it OK to mention it during the interview/ Give them new application form with correct dates? Will they deny visa because now our plans are no longer fixed?
