+1 to the comments about not keeping it in the country.
Bear in mind that HSBC Offshore (or in any other country for that matter) bear no relation to HSBC in Dubai, other than the name and logo. They're like franchises. The real problem with HSBC in the UAE is with the UAE and Middle Eastern banking. Which is why every single bank in the UAE is complete crap. Lots of guys get pushed to the point of desperation and switch from HSBC-Lloyds-Barclays-etc and it makes no difference, they are all regulated under the same backwards, archaic, idiotic system.
So just pick one that has a branch near your accommodation, grit your teeth, and keep counting the days until you can return to a real country.
