U have to wait till the new list of eligible occupations comes out by July. your profession, IT is not on the current list. Another way around it is to have an offer of employment from a Canadiam employer.
to apply for PNP program of Quebec, you'd need to demonstrate your language skills in French.
The door is simply closed for IT for an year from now.
only hope for you is AEO .
if you could collect AEO, then it woulnt matter from which NOC it had been issued by your employer in Canada. AEO is something often Canadian employers dont like to go after unless the applicant poses a valuable knowledge and this could bring them lucrative corporate gain. Canadian employers can get employees at a good number within Canada but there are exceptions when they hire from outside using AEO.
you can talk to noted immigration consultants about that in London. do let us know what they say in London.
Which place are you residing at the moment. And I will let you know for sure. I have already made a list which I need to contact. Just in case if you have some noted consultants notify me, it would be really apprerciated.
