slightly the other way around. If you hold a UK IR, all you need to get an FAA IR is to complete a written exam. Make sure however that you ask for the shortened written paper for foreign pilots. Cost $88 to take. Then take your pass certificate to FAA flight office and they will issue the FAA IR - no flight test or oral exam required, and no other charge made.
This can be added to an FAA Pilot Certificate gained again by going to the FAA flight office, with licence, logbook and passport in hand, fill in a form, wait 20 - 30 minutes (no charge made for this) and walk out with a temporary certificate. About 2 - 3 months later by post, will arrive your FAA certificate. They will post it all the way to England no charge.
Just thought somebody might be interested.
