If you are looking to work in regulated jobs in Sweden, you might need to get your academic qualifications approved by the Swedish Council for Higher Education (UHR). For jobs in healthcare, you will need to apply through the National Board of Health and Welfare (Socialstyrelsen). They will check your credentials to see if they meet Swedish standards and might recommend some extra training or tests.
You will usually have to provide certified translations of your diplomas and transcripts. For non-regulated jobs, many employers accept international degrees, especially if you have the right experience. Getting your qualifications validated makes sure they're recognized here and can help you find a job more easily.
