NP. You should check your visa eligibility - it is great if your Passport gives you visa free entry into the UAE. Otherwise, you have 2 options:
1. Apply for a visa at the EK Desk (free of charge) in the arrivals hall and endure a wait of 2-3 hours.
2. If you are eligible for a Visa on Arrival, walk over to the Marhaba desk on the opposite side and they will issue you a 14 day visa for AED 200.
