Twin Aisle not strictly true. I am an HSBC Premier customer in the UK. When i opened my account in Dubai with HSBC a recommendation was sent from my premier Account Manager in the UK and i got a Premier Account over here straight away. No problems at all. The great advantage with the Premier Account is Global Banking. It means you can go online to do your banking, and both your UK account and UAE account will appear side by side. You can transfer as little, or as much as you want between the accounts. It costs you nothing for all transactions, and it happens immediately.
HSBC have been nothing but helpful, and the product is perfect for an ex-pat.
Works for me anyhow
