According to the article on the 2nd link from my first post, they mentioned that they have relaxed the conditions. Maybe you should give it another try.
I will applied and got my application approved but have not return to Malaysia to receive any of the incentives yet. And i do not have 5 teenages kids!!
I have about masters in engineering with about 7 years work experience.
With regards to whether the niche job is available or not... It does specify that you have to work for 5 years in M'sia after receiving the incentive but
no mention on what field of expertise you must to be working on.
As usual, made countless phone calls have provided me with contradicting information.
