Santosh, doucments that you are highlighting are good....Please check if your work experience qualifies the following requirement
Skilled work experience
Your work experience must be:
- in the same type of job as your primary NOC
- within the last 10 years
- paid work (volunteer work, unpaid internships don’t count)
- at skill type 0, or skill levels A or B of the 2016 National Occupational Classification (NOC)
- at least 1 year (1,560 hours total / 30 hours per week), continuous:
- full-time at 1 job: 30 hours/week for 12 months = 1 year full time (1,560 hours)
- equal amount in part-time: 15 hours/week for 24 months = 1 year full time (1,560 hours)
- full-time at more than 1 job: 30 hours/week for 12 months at more than 1 job = 1 year full time (1,560 hours)
with it being said, also check where do you stand with your CRS score...
