Well,regarding job vacancies (as far as I know) whether it is in winter or summer the hassle is the same (unless you are a doctor..as they badly need doctors there). If you are in a specific field, upon arrival you won't get the job you are looking for straight away..you need patience..first get any job suitable to you to have an income and start building your credit history and also meet as much people as possible to build a solid networking..then it will be easier for you to find another job in your specific field.. please visit the below website for job offers. You will have an idea in which fields they are recruiting the most
