Thanks for your reply. Yes. I have checked the entry requirements for Croatia and if we have a multiple entry Schengen visa then we will be able to enter Croatia based on that.

But if we get only a single entry Schengen visa then we'll have to stay at the airport. That's why I wanted to know what is process for international transfer at Dubrovnik DBV airport.

Does DBV airport have a secure international to international transit zone? Do we need to go through passport control?

Are there any lounges we can access for Star Alliance Gold in the international transit area?

This will not be an overnight connection. But if we can we want to visit Dubrovnik in transit if we have the multiple entry Schengen visa, if not then we'll need to know if we can make international to international connections at DBV airport.
