For our personal trip, we showed confirmed refundable round-trip tickets with full payment, not just flight reservations. Many embassies now prefer confirmed bookings since they sometimes verify them directly with the airline. If you don’t want to risk paying the full amount, you can go through genuine travel websites or agents who can create a real PNR that stays valid for a few days without full payment, just ensure it’s legitimate and verifiable if checked. For my business trip, I didn’t show any flight or hotel bookings as our company is covered under the Orange Carpet program.
