Having written that it's not the answer you are seeking.

I assume you want to host a .com in the UK? I have quite a few domains all running under a mixture of .com/eu/uk/cn/in/asia/etc and all hosted in the UK.

They all do well in the markets they represent, the .in does especially well because English is a subsidiary official language and is very widely spoken and used at many levels, especially business.

The .coms single-biggest traffic sources have always been the US with about ~40% of overall traffic, in comparison the UK is about ~5% of the overall traffic.

Is this a well-established .com site already ranking well? If so I doubt you would have many on-going ranking issues in the US however a new .com launched from the UK may find it very slow to gain a foothold in the G.com SERPs.
