Transfer

an a dependant  wife do a remittance anywhere  in the world from Saudi arabia?
without info. of her husband to save her personal savings


2nd..what documents are required for a wife having dependant iqama/residence permit to open a bank account?
Like

1) Yes after showing your Iqama at the exchange
2) Yes with your sponsor i.e. husband's permission

1...she was told she cant do remittance on dependant iqama....kindly name a specific bank/branch or remittance centre in ksa

That is strange.  I have had families of colleagues transferring money without issues in the past from standard money exchanges in malls.   Unless something has changed recently.
