Hi, I just experienced my self in this regards that conversion only be permitted if you have not done any test at the driving school. If you had a record that you failed, you may still need to go through the process till you pass so this is not applicable to everyone. Only to those who have not undergone any test, yes you can do so provided you have all your necessary documentation from your employer e.g.: NOC Letter and etc etc

That is very tricky part of the article. I even saw few people from the U.K. Trying to convert their license also got rejected
