Problem in loading cities using JSON

Question

I am using Geonames for loading the cities using JSON. Geonames data i imported into my database. I am using MS SQL 2008 Server. I display a dropdown for country select. Once the user select the country. I am loading all the cities into the autocomplete textbox. I am facing a delay in the getJSON method. Also it seems like executing asynchronous. So before getting all the data my autocompelte is getting filled. Below is my complete script. I think i have some problem in the loop. Please advice me what i am doing wrong in my code.

$(document).ready(function () {

    $("#ShowLoad").hide();
    //Hook onto the MakeID list's onchange event       
    $("#Country").change(function () {
        findcities = [];
        $("#ShowLoad").show();
        $("#HomeTown").unautocomplete();

        var url = '<%= Url.Content("~/") %>' + "Location/GetCitiesCountByCountry/" + $("#Country").val();
        $.getJSON(url, null, function (data) {

            var total = data;                                
            if (total > 0) {

                var pageTotal = Math.ceil(total / 1000);
                var isFilled = false;
                for (var i = 0; i < pageTotal; i++) {
                    var skip = i == 1 ? 0 : (i * 1000) - 1000;
                    var url = '<%= Url.Content("~/") %>' + "Location/GetCitiesByCountry/" + $("#Country").val() + "?skip=" + skip;
                    //alert(i);
                    $.getJSON(url, null, function (data) {
                        $.each(data.Cities, function (index, optionData) {                                
                            if ($("#Country").val() == "US") {
                                findcities.push(optionData.asciiname + "," + optionData.admin1_code);
                            }
                            else {
                                findcities.push(optionData.asciiname);
                            }

                        });

                        if (i == pageTotal) {
                            //alert(findcities);
                            $("#ShowLoad").hide();
                            $("#HomeTown").focus().autocomplete(findcities);
                        }
                    });

                }

                $("#HomeTown").setOptions({
                    max: 100000
                });

            }

        });

    }).change();
});
