user migrate

var user_migration_error = [];

function user_migration_save(user) {
  user.save(function(err) {
    if (err) {
      console.log(err);
      console.log(user.email);
      user_migration_error.push(user);
    }
    else {
      console.log('well done ' + user.email);
    }
  });
}

exports.migrate = function(req, res) {
  var url = 'http://intranet.xoxo.com/beta/users';
  var users = [];
  request(url, function(error, response, html){
    if(!error){
      var data = JSON.parse(response.body);
      for(var i in data) {
        //console.log(data[i].uid.content);
        var user = new User();
        user.provider = 'ldap';
        user.name = data[i].name.content;
        user.username = data[i].name.content;
        user.email = data[i].mail.content;
        user.uid = data[i].uid.content;
        //Roles
        if (data[i].rid) {
          user.roles = data[i].rid.content.split(',');
        }
        ....
        ....
        ....
        user_migration_save(user);
      }
      res.jsonp(user_migration_error);
    }
  })
}

I want to execute this -: res.jsonp(user_migration_error) synchronously ,basically only after the for loop is over

But it gets executed asynchronously, and the users which couldn’t be migrated are not populated on the screen. Things are working perfectly fine in the backend, just the output on the screen is wrong.
