Hi,
As you score 390 CRS score, currently it is considered as quite low score to immigrate to Canada. Hence, it is important to improve your overall CRS score. The CRS (Comprehensive Ranking system) scores are given on the basis of core human factors, skills transferability and additional factors.
As far as your experience is concerned, you must have experience in same NOC, then you can gain maximum points. Getting experience from different occupation does not considered as same work experience. Hence, it is advised to gain more experience in Sales person profession. In addition to this, we are giving some of the measures through which you can improve your CRS scores as:
• Retake IELTS exam. If possible, improve French language.
• Apply for Provincial nominee program. This will give you additional 600 points.
• Get Master’s degree in your Education.
• Get a job offer letter (LMIA approved)
• Add points if your any siblings or relative living in Canada.
All the Best!
