This subclass 491 visa of Australia allows skilled workers to live in Australia and work in the region for five years as they enjoy the opportunity to become permanent residents after three years. Eligibility conditions include applicants’ age being less than 45 years, a pass in the skills assessment in a nominated occupation, satisfactory English proficiency requirements, scoring at least 65 points, and securing nomination from a state/territory or a family sponsor. Submit the EOI via SkillSelect and wait for Invitation to Apply (ITA); collect all the documents required and submit the application. The higher the points a candidate scores, the more relevant experience they have, and the better his or her skills will fit the actual needs of the state, the better his chances of getting approved.
