How to loop through JSON object with an array inside in Jquery/Javascript?

I want to loop through an JSON object based on the amount of items in “nationality” that I retrieve with an AJAX call in JQuery. The problem is that there is an array inside my JSON object that I also need to loop through. At the moment I get undefined or can only print the company name.

JSON response I retrieve:

                    var data = JSON.parse(response);

              $.each(response.nationality, function (i, item) {
