Dariwal,

              Actually When i applied for PR they didn't required the IELTS score. But few of my friends who migrated to canada told me that these days they do require a proof of english proficiency i.e IELTS score and some of them were let go with the degree from US universities. So I really do not have an specific answers to it but to be on safe side would suggest folks to take IELTS. But if you really want to try it submit your degree and see how they answer it. By saying so please give your self enough time for them to get back to your before being illegal in the US. This might effect your application process.

Employee,

               now a days it takes 14 months to get your PR card once you submit your application. i.e if they don't have to sent your application back for being  incomplete i.e no IELTS results, no police report, sending personal check (they require money order) for application fee.
