My husband has a Chinese passport and I am a U.S. citizen; I don't need a visa to travel to Schengen countries. I am helping him to apply for a visa. Our plans are to go to Paris, Italy and Spain, but we haven't nailed down definite dates; the approximate dates are August 18 to September 11. We made an appointment with Spain consulate to apply for the visa. We need to show air flight reservations, I could book it online without any problems.
Since we don't have definite dates, what dates should he put down on the application? I know that, once they approve you, they give you 90 days, so does it matter what dates I put down on the visa application?
Our appointment at the Spanish Consulate is in a few days.
