Okay so you just received a standard form email that everyone who applies to CNO receives. Successful completion of Jurisprudence is only "part of your application for registration". So you can complete it at any point going forward (once you activate your account).
After completing this exam you will wait for CNO to let you know what your next steps are. They will send you a letter stating that you do or do not meet the education requirement. Please be warned that the letter which you will likely receive is terrible and harsh. They usually start in bolded letters "You do NOT meet the education requirement". Incredibly unprofessional. From there, they will likely as you to provide some information about your past and/or present nursing work experience. Some documents will need to be signed and completed by your nursing employers etc. Then they will assess whether the work you have done proves that your education is equivalent to a Canadian education. If they decide no (which is likely if your only nursing work experience has been in India) then they will ask you to do the IENCAP exam. It costs $500 and consists of a whole day of testing. Half of the day is a multiple choice exam and the other half is 12 stations with patient actors and nurses who watch you assess and treat the 'patient'. It takes months to get a spot in the exam so as soon as new exam dates open up I recommend you register right away. If you pass that test then you will have met the education requirement (it takes at least 8 weeks to get the results). Then you will get a letter saying which requirements you have and have not met. Once you feel you have met them, you can apply to for your license and await their response. I will warn you that some people have waited forever.
@Legentellison has been waiting forever. If you try to call CNO you will be on the phone waiting in line for up to 4 hours. It's a really rough ride so my best advice is to be sure that you want this really badly before proceeding. I wish I had known all this when I first began. I hope things get faster for you and others beginning the process.
