IEN in Canada

hi!

I'm currently working here in Abu Dhabi UAE, and I applied for CNO for my eligibility to sit CRNE. It has been 6 months since I sent my documents together with the application package still they haven't sent me the assessment letter. they are asking for an Ontario application number. what is it? how will i get an application number?

I'm currently processing my immigrant visa, hopefully it will be available by next year. I'm also planning to repeat my IELTS next year since I only got 6 in my writing during my IELTS last april.

please enlighten me on what to do next. I have been sending CNO numerous emails and called them, according to them they already have sent the assessment letter, but a did not receive any.
