I am waiting for the approval of the talent visa, can I apply for the high talent visa at the same time?

Yes, but the approval time for the high talent visa is much faster than that of the talent visa. Both initial visas are for two years, so if the high talent visa is issued, there may not be another talent visa issued. Applicants can only choose one, and finally re-enter the country with the confirmed visa.

If anyone has previously applied for the talent visa, they can discuss with the agency whether they can apply for the high talent visa directly at the same time. Our team has provided free high talent application services for previous talent visa clients.
 

Now it is the specialist/talent/iang visa. After the high talent visa is approved, can the time be counted together for the 7 years of permanent residency?

We have confirmed with the immigration department that it is possible. As long as the high talent visa is issued before the original visa expires, it can be counted towards the 7 years of the original visa.
