For getting Balidiya signature, you need kahramaa also in your name. Now it is all in computer system. So we cannot cheat Balidiya or Kahramaa. So best thing would be to take an independent house for rent - get all things done perfectly to get the RP for your wife and kid. That is the only way to do... Later on after getting RP, you can change the house if you like. That is left to you...
