In my opinion if they have reached their quota for the year, I don't think they will open the EOI window nor will they be accepting EOIs until they are done going through the current applications received and issuing nominations from those applications.
I hope, though, that I am wrong and - especially for all those who have recently attended info sessions - that the window to submit EOIs does open again in this year, in this month or the next.
Good luck to everyone and please do keep monitoring the NBPNP website for updates!
