You can be holding passport of these country, but if you don't have a valid driving license from them, you still need to take the test. I have two passports from these list of countries and I still took test and passed it. If you have confidence to drive you can pass the test easily. Btw did you see how the drivers that are from other than the countries mentioned on the list above. After they receive their drivers license, they drive like idiots, no signalling, drive in the middle of the lane, don't know how to over pass, drive extremely slow causing traffic jams (because thy all drive the same). Here in Qatar you really need to master defensive driving skills and most people who doesn't come from the above country don't know how to master defensive driving, causing accident and unnecessary traffic jams.
