A 190 visa is based on points, if you cross the cut off that has been set, you are eligible then only. All the skilled workers and people who think that they are eligible for applying for this job or we can call it a post as well, they get nominated by an Australian state or the government territory and then after they have gotten it, they can be the residents in Australia permanently as well. They say that these people can therefore live in Australia on permanent basis then.
For them to become eligible, they have to have a relevant occupation on the 190 visa migration agent Perth occupation list, without which they would not stand a chance in getting it or being eligible for this at all for that matter as well. Like any other job, the people applying for or being selected by the Australian state for that matter have to have the suitable skills that are necessary for the occupation to be granted to them as well. There is an age criterion too, that is people who can work for this post have to at least be 18 years old and can be up to 44 years old, but other people who are either younger than 18 or older than 44 years do not have a chance in getting a chance to be the one who gets the job basically then.
Each state or the territory government has its own list of occupations that are in demand in their specific area or state we can say. There are many various requirements that have to be fulfilled in order to be able to stand for the post. These requirements include the person to have some work experience, a respectable background and strong ability of speaking English as well. They have to then submit an (EOI) that is an expression of interest through Skill Select with all the details of the occupation that they have nominated for and all the skills and other qualifications and credits that belong to them as well. The Skill Select would calculate their score and help them evaluate the best candidate in the end. If the score you get is a high value, then only would the Australian state or the territory would see you EOI and think of nominating you. Let us understand it like they have your application shortlisted if you get the high score through Skill Select and after that the state looks at your shortlisted application and decides of having you on the occupation or not. Because in the end the decision is with the state or the territory as no one can influence them.
