So far only two applicants for now who opened up in this forum have submitted their EOI forms before 8.30am (12am & 1.15am) and did not receive any response from NB about the status of the submission, the same thing happened to the other applicants who have submitted their forms after 8.30am and did not receive a notification that the quota is already filled for this month. Therefore, as per my observation in today's scenario, an applicant can submit EOI form anytime as long as it falls on the 1st til 15th of the month.
So I guess and hope that all applicants who did not receive a reply/notification from NB about the quota being filled for this month were successfully accepted and will be on the queue for the selection process for the first batch of invitation to submit the NBPNP full application package.
tnx
