It only shows you that you are eligible, qualifications wise, to gain an employment pass. It does not, however, guarantee you a job here. The employer STILL has to apply for the Employment Pass and the employer still has to justify why he has to hire a foreigner to do the job. This is getting to be the hard part. So even though you have the necessary qualifications you still can be rejected if there are sufficient locals with the necessary skillsets in the industry you are trying to penetrate. (Of course, it sounds like you are going into a new area that wouldn't have had time to get saturated yet with locally trained individuals so you may be in luck. But you still need to remember that there is a recession going on and the employers are using that to screw everybody, left, right & centre!
I believe you are thinking of the LPR (Landed Permanent Resident) which is an entirely different kettle of fish.
SOME PEOPLE TRY TO TURN BACK THEIR ODOMETERS. NOT ME. I WANT PEOPLE TO KNOW WHY I LOOK THIS WAY. I'VE TRAVELED A LONG WAY, AND SOME OF THE ROADS WEREN'T PAVED. ~ Will Rogers
