hi there, im a dentist from India and applied for 489 visa. Most of the people dont have much information regarding dentists.Its not necessary to clear the exam for immigration purpose but only to practice dentistry. But getting your degree assessed is most important. Get a good score in PTE and get your degree assessed from your dental council after that you can apply for a temporary visa as our occupation is in the STSOL. I got state nomination approved from Queensland and applied for the visa in March. Im preparing for the preliminary exam as well. Still waiting for the visa though....
