You know, when you want to get information from Oklahomans, adding insults might not be the best approach. :s
And, by the way, those who have to take nothing more than an eye exam for an Oklahoma license are those moving into Oklahoma with a valid license from another state. Wisconsin does the same thing for those moving into Wisconsin. If you start from scratch in Oklahoma, getting a license is considerably more trouble, just as it is everywhere else in the States.
Regarding changing an OK license to a local one, yes, that can be done unless something has changed in the past few years. You’ll still need the health check, though.
But if you want a scooter license as well, you’ll need to take the scooter driving test. In OK people need only one license for both cars and motorcycles; but in Taiwan they won’t let you get both automatically. At least you can skip the written test for scooter licenses.
The local DMV has a booklet with photos of valid driver’s licenses; so the person behind the desk will probably look up the Oklahoma one there. There’s a good chance, however, that the booklet has not been updated since OK changed its license format several years ago, so be prepared to argue that your OK license is indeed real. I recommend going in armed with printouts of sample licenses from the official OK bureau; make sure the URL is on those pages so the people there can look it up for themselves if they need additional reassurance.
For that matter, you should probably bring with you a copy of the page on the local DMV’s own website that says OK licenses can be traded for local ones. And don’t forget your passport and ARC. The people in the office will probably date your license only until the expiration of your ARC, which is wrong but good luck convincing them otherwise.
