For some people, NNAS has taken a month (I've actually only heard of one person for whom this was the case) and for others, it has taken a full year. For most, it falls somewhere in between 4-8 months. You will likely be asked by CNO to take the IENCAP and if you have been successfully working as a RN in the US, passing this shouldn't be an issue for you. But it will take time to get to that point where you can take the exam.Thanks I was thinking of worst case scenario where it takes 2 years (I saw few folks in forum complaining about 1 year of NNAS) as i am going to work till next year end but I can't work after that because of visa expiration. That's why i applied via express entry to move to Canada. Its a long wait for Green Card in USA for Indians and visa sponsorship is another headache for me. Hopefully 1 year is a good time to know where I am in terms of processing.
