4.
Manitoba- They have changed the entire process. Now, proof of strong connection to Manitoba is MUST, to qualify under this new points based scheme. One can show strong connection in 3 ways - 1. By studying in a Manitoba based institution, 2. Working in Manitoba for atleast 6 months (outside province students) or 3. Have a relative or close friend who is PR/citizen residing permanently in Manitoba nominate you. Students of Manitoba means to be a student studying a minimum 1 year course in a recognized Manitoba based institution. All MUST apply under points criteria, where one MUST score minimum 60 points. No work ex or finding a job required for Manitoba students. Perhaps the easiest route, if one already has 60 points. In-case, if Manitoba based student is falling short of 60 points, then must find any job, do it for minimum 6 months, and get points for Manitoba work ex under Adaptability.

5.

Should have a full time skilled (NOC O,A or B) job offer. The job offer must be from an approved employer. There is no need to work for certain number of months.
The BC PNP will also consider applications for positions under Skill Levels C and D of the NOC Matrix where the employer can demonstrate that there is a structured plan for career progression to an occupation at Skill Level 0, A or B. Nominee applicants whose eligibility is based on a job offer in a NOC C or D occupation may be required to submit a language proficiency test.

There is another Entry Level and Semi-Skilled stream for foreign workers, where NOC C and D jobs are usually considered under 2 years pilot project in Northeast Development Region of B.C for 3 specific sectors -
•Tourism and Hospitality
•Long-Haul Trucking
•Food Processing
where, applicants need to gain 9 months work experience. So, students after getting PGWP..can go for PR via this route too.
To know more about this B.C PNP pilot Entry Level and Semi-Skilled stream see:

6.
Saskatchewan- Rules remain same as before for students applying to SINP under job offer stream (any job with 6 months work ex. for Sask. students and min 1 year work ex. for outside province students)) OR Sask. Master's/PHd stream (no job offer required, provided one meets certain conditions)
BUT they have applied Quota to their student and other immigration programs. This means every year only a very few limited number of students can apply on 1st come 1st serve basis. Has become very tough now to compete and qualify. Right now, according to SINP website: The SINP has reached the application intake threshold for out-of-province post-secondary graduates. No further applications will be accepted. International graduates interested in obtaining permanent residence status in Saskatchewan are encouraged to explore all provincial and federal programs for which they may be eligible. Hence, now SINP/Saskatchewan is no longer an option for easy PR.

7.
Quebec Programs -
Quebec graduate stream (PEQ) 
o any 2 acd. years/ 1800 hours UG diploma course or 2 UG courses combining to total 1800 hours of study in Quebec, or Bachelor/Master/PHD degrees.. in Quebec in FRENCH medium OR if studies done in English medium then show minimum intermediate level FRENCH language proficiency.. like passing DLEF B1 exam (with required marks of 16/25 in Listening and Speaking and overall minimum 50/100). Then once can qualify for direct CSQ/ Quebec selection certificate within 20 days under this stream . No questions asked but French intermediate level compulsory. In reality one of the easiest PR programme.. no work ex or job offer needed nor need to wok for any number of months... nothing.
http://www.immigration-quebec.gouv.qc.ca/en/immigrate-settle/students/stay-quebec/application-csq/students-peq/index.html
Quebec Regular program : Foreign student in Québec studying high demand qualifications which are less than 1800 hours/2 academic years can qualify under this route. It is a points based stream where French was not compulsory till Dec. 2012. BUT from Jan 2013, Quebec govt. amended their charter of language, where ALL immigrants MUST know minimum Basic DELF A1 level proficiency... and so as of now, applicants MUST have atleast basic DELF A1 level French proficiency. One must get minimum 49 points to get called for interview (where remaining 6 points will be given on adaptability factors) or directly get min. 55 points so as to get direct CSQ without interview or need for any adaptability points. One must study a minimum 12 or 16 points category Quebec qualification (see List of Area of Trainign pdf document) to qualify under this stream. It's comparatively a lengthy route with long processing times.

To know about High demand qualifications for applying under regular program see List of Area of Training:
http://www.immigration-quebec.gouv.qc.ca/publications/en/diverses/list-training.pdf
It is anticipated that Quebec immigration rules will be revamped after 31st July 2013, and they MAY make minimum French level 2 or 3 /i.e DELB A2 or B1 level compulsory for all students. Will have to wait and see.
