If the official length of your program of study is:
1.less than eight months
you are not eligible for this program
2.less than two years but more than eight months
you may get a work permit for a period no longer than the length of your program of study (for example, if you studied for nine months, a work permit may be issued for a period of nine months)
3.two years or more
a work permit may be issued for three years
**** You have been placed in 2 category.
Loads of people who completed program in 16 months are granted 16 months PGWP in past.
I think it depends on your luck.
My friend just got his work permit of 3 year [ he completed the program in 16 months ]
You can give a try by applying again. But i don't think it will be helpful.
And please next time don't write in Block letters. It is considered as rude and harsh.
Good Luck.
