Hi ri123
MPNP approval is based on your job what you worked for. Based on which you will go ahead and apply for PR.
I know it hard but its either long time with ease or short time with difficult situations.
I took the longer route because after working for an employer for 7-8 months if made excused to give me employment letter and get the job approval from SINP. He made it so difficult for me that I had no other option then leaving the job.
I started another job (with everyone's blessing got good job), completed my probation period and my manager (Such a nice and down to earth person) got my job approved and I applied for SINP NOV 2014.
Got my nomination in April 2014. Rest check my timeline.
I had 3 years work permit - enough time so it worked out.
Make sure you take a right decision as you will have to inform MB immigration and it depends on them if they renew you job and how long its gonna take.
All the best buddy.
