Thanks, Skill Assessment and PTE is positive. My employer's immigration agent quoted as below "You may want to consider that, according to Immigration the average processing time for a Subclass 186 ([DE) Visa is between 13 – 18 months, whereas the average processing time for a Subclass 186 (TRT) Visa is 12 – 13 months."
On the contrary, 2 of my friends got 186(TRT) visa in 4-5 month and one friend is stuck with 186 ([DE) from last 10 months. So again, Shall I wait another 6 months to get eligible for 186(TRT) or apply 186 ([DE) right now.
