Migrationsverket, the Swedish Migration Agency, acts as the gatekeeper for immigration and citizenship matters in Sweden. Their primary responsibility is to:

Process applications for residence permits: This covers various scenarios, from people seeking work or studies in Sweden to those reuniting with family or applying for asylum.
Evaluate applications for Swedish citizenship: If you’ve met the eligibility criteria for becoming a Swedish citizen, Migrationsverket will assess your application.
Issue travel documents: They handle the issuance of residence permits that function as travel documents for some foreign residents in Sweden.
Provide information and guidance: Migrationsverket offers guidance on the legal requirements and procedures for various immigration processes.
In short, Migrationsverket plays a crucial role in managing Sweden’s immigration flow and determining who gets to call Sweden home.
