My son is 29 years and a Hotel management graduate and having six years experience?

Information for applying for permanent residency is on the Citizenship and Immigration Canada web site. This includes requirements, fees, processes, processing times, forms, etc.

In order to apply as a skilled worker, he would require a job offer from a Canadaian company in a type 0, A, or B profession listed on the National Occupational Classification database. Chef is a type 6 and does not qualify one to apply for permanent residency. Hotel manager is a type 0 profession. However, finding a job as a manager in Canada without a full (four year) business degree is likely a non-starter and equally importantly without an undegraduate degree he is unlikely to obtain the minimum 67 points needed to apply -- and you typically need in the 80s to be able to compete for one of the 10,000 positions.

There is a self-test on the CIC web site which will give one an idea if they might qualify for permanent residency.
