Is it reliable to immigrate to South Australia after three years?

What do you mean? After studying abroad for three years?

Studying abroad depends on your major (50-60) and age (at most 30 points, it seems to be between 20 and 33 years old, I don't remember the details. . . Sorry) There are other auxiliary items in your IELTS score for immigrants (7 points and 25 points) ... But in South Australia, immigrants get 5 points, and all the points add up to 120 points, so you can immigrate. If the newly graduated immigrants don't get enough points and work full-time for one year, the score seems to be 15.
