FYI, All the Employment categories are closed except "Employer Job Offer: In-Demand Skills". If you have job and is one of "In-Demand Skills", it's better to apply. Considering your score around 420,although if you would gain more points by IELTS, that won't be sufficient as the EE score is fluctuating abouve 450-460. This might change (decrease) by year-end if they don't achieve the nominations for the year. You can still fill EE profile, and if you can, apply for OINP. If you're on work permit and going to expire this year, then EE is your best shot. AS OINP is closed for International graduates, Foreign worker streams.
P.S: You can have both profiles, but if you get nominated you'll have to delete the other profile, for sure.
