Sorry for disturb you all. However, I have got the answer by go through all of these thread. I was known that I can apply NOC 4152 when I don't have degrees or certificates on social work.
However, the organization I worked before was Pearl S. Buck International (PSBI), a services provider (as it has adoption services).
Although in my country, PSBI is obsolutely an INGO. I worked for the "Inclusive Education for the Hearing Impaired and Deaf Children" and my job was exact the same as duties of NOC 4152, but someone said to me that because it is a services provider, I am not qualified to apply NOC 4152 even I do exact the same job as a social worker. Is this true?
Anyone can help me with this? Thank you very much and wishing you and your families a very Merry Christmas and a Happy New Year.
