I inquired these things with a consultant. My plan will be to
1. apply for credentials (fine with masters, ielts, i suppose; Please state the risks involved .........)
2. visiting visa to Canada to write the exam (what percentage chance of getting a visit visa to come to Canada and write the exam, Please state the risks involved .........)
3. Write the theory (Will pass if i work hard, Please state the risks involved .........)
4. Within six months i need to pass the practical (How long will visiting visa allow me to stay? Is there any chance to find an employer with theory alone, will canada goverment give me a work permit with this, Please state the risks involved .........)
5. Get an employer (I heard that employers prefer people with PR, Please state the risks involved .........)
6. Labor market opinion (I heard that it is very very difficult to get a labor market opinion as there are already many immigrants inside canada Please state the risks involved .........)
7. Work permit (Please state the risks involved .........)

this is a very risky option, but no other constructive way to be in canada. Please help with your feedbacks
