Will it take 6 to 8 months to switch from Australia 820 to 80 1 in two years?

Yes, the standard trial time announced by the Immigration Bureau is 6-8 months. However, under normal circumstances, there is no problem in transferring from 820 to 80 1, and the immigration bureau will not conduct an investigation, so the visa will be issued in 4-6 months. However, if you don't write an email within six months, the effect will not be great, because the immigration bureau will say that it is within the standard trial range. So wait patiently.
