Hi Malkait sir,
my question is can i claim any points under smc with one and half year nz skilled work experience as chef ( no overseas experience) for eoi as i am stucked with 150 points.
In order to claim points for work experience, you need to have a minimum of 2 years of work experience. As you already have 1.5 years, it is not long that you would be able to claim your work experience points. I would recommend you to start looking into meeting other requirements e.g. IELTS/PTE etc. so that you can be ready and submit your EOI as soon as you complete two years.
