Angtao, be very careful with any agent or `professional`who claims you to get an LMO or a job as a foreign worker. I heard and know to many bad stories of people being ripped off and left with nothing- no actual job and few thousand less. Never pay anyone to get you an LMO ever. What I did when I was done with my studies, I did research all the companies in town who employed foreign workers and went with my resume to each and every of them. That`s how I got a job, not the most fancy one, but it helped me for 3 years to tay here and establish my life.
Only an employer can obtain an LMO for you from the HRSDC, they have to apply to get you one.
