You need to use the full file path instead of a relative one.

Use the WordPress function get_template_directory() to get the path to your template directory. From there add the path to your file.

var_dump(csv_to_array('csv/nationality-codes.csv'));

To:

var_dump( csv_to_array( get_template_directory() . 'csv/nationality-codes.csv' ) );
