I am planning ten days in Paris, Brussels and Amsterdam in October, with a day-by-day route, refundable hotels and a return flight, and I am preparing an application from India. I feel anxious that my form, bank statements, leave letter and bookings will tell different stories, so I want to reconcile dates, budget and transport before submitting.
Start with the genuine main destination and responsible consulate, then make the form, itinerary, funds, employment or study evidence, accommodation, insurance and transport support the same dates and purpose. Checklist: passport, local form, requested photographs, financial history, leave evidence and bookings or reservations allowed by the instructions; explain any unavoidable variation briefly. Do not inflate funds or invent reservations, and verify local requirements because document lists and handling can differ.
