Hi Bhavin4,
This is the normal process Nova Scotia has followed. Looks like you didn't get chance to follow the posts & discussions our seniors have posted in this forum for last 2 years.
Coming to your questions, you can create a new EE Profile & Job Seeker Code and provide it to your Case Officer but expired IELTS will be a huge challenge for you. Try looking for the earliest IELTS Test Date and book it, moreover, try convincing your case officer to provide additional time to provide new IELTS Score Card. I don't want to disappoint you, but your case officer might choose to close your case if he is not satisfied. All the Best!
