Yes and I dunno why a resident in Hong Kong or Australia would trade with IB UK, they should be trading with IB HK. IB usually make you trade with only the local IB office of your residence.
This situation could arise if you opened with IB-UK while residing in EU and later moving away. Also, not sure, but its possible IB-UK is older than IB-HK and residents of HK would have gone through IB-UK back then.
In order to 'switch' to IB USA LLC (away from IB UK) you need to file a new application and start anew. This would also introduce a bunch of problems. Aside from complete account re-configuration (including trading permissions, etc.) all trading records would be 'lost' (as they would be bound to the original account and not the new account).
So for those who need to generate reports, they will have to 'merge' old reports with new reports.
And if there was any benefit for being a client for a long period of time, those benefits may be lost. (Not sure if there are any, but its nice to see client for 10+ years, as opposed to 1 month )
