Try to send RequestVerificationToken from headers if you need yo add antiforgery validation.

 $.ajax({
                url: '@Url.Action("SaveUser", "PersonalInfo")',
                type: 'POST',
                headers : {
                  RequestVerificationToken:
                      $('input:hidden[name="__RequestVerificationToken"]').val()
                },                   
                data: JSON.stringify(UserVmodl),
                contentType: 'application/json; charset=utf-8',
                dataType: 'json',
                async: true,
                success: function (data) { localSuccess(data); onSuccessFunc(data); }
            });

Remember to add @Html.AntiForgeryToken() in your form. Besides,you need to return a json result since your ajax needs a return type of json.
