Even though I am not a native person, I am currently living in Australia, Adelaide. So far, it's been very good challenge and experience for my life in Australia.
I have been here almost 8 months and aiming for parmanent residency in the near future so I am preparing to apply for the course in tafeSA which is governed by the Australia government.
I do not have any idea about Costa Rica, your country. However, In South Korea where I came from has a big problems at the moment. In fact, there are people who graduated from university and they do not have a permanent job or any job due to the lack of demand to the people. Morever, it is getting worse and worse to survive in South Korea.
On the other hand, In Australia, there are planty opportunities to get a job and make a own business, and the Australian government looks after public people very well, for example if you lost your job, the government gives you some money for keeping life and helps you to find another job what you might want.
Moreover, the hospital,madicine store, and dendist's are absolutely free. You might do not believe what I am saying like I had done but it is true and I have found that this country is the best country in the world.
If you are currently having your own skill and willing to live in Australia with your good English, it would be absolutely a chance to change your life.
