Just to emphasise that general advice is a 2 year course that then qualifies for a 3 year PGWP given a one year assumes you get a skilled job on day one, not always possible. Also of benefit to get a job classified as NOC 0,A or B.
Only attend a public college given private colleges would not qualify for a PGWP.
So is PR easy , no it is not, it requires a great deal of effort , personal and financial investment over a few years.
