Can IT personnel immigrate to Australia to be engineers?

Yes, first of all, you have to pass the EA evaluation. The evaluation of EA does not depend on your postgraduate major, but mainly on your major in this science. If you have a bachelor's degree in engineering, you can apply for e a assessment now. However, it will take at least three years for overseas skilled immigrants to be approved. In this case, you can try an employer guarantee or a four-year business visa, which should be faster.
