If they speak Swedish, and contribute to the society they could be. But if they live on handouts and stick within in a subculture they are just destroying the country as George Soros intends.
I'm not sure you can tell if they're a freeloading terrorist just by their name and their skin color.
If you wish to become Swedish you will need to apply for naturalisation. To obtain Swedish citizenship you must meet the following requirements:
Be at least 18 years of age.
Have permanent right of residence in Sweden.
Have lived in Sweden for at least five consecutive years or two if you are a Nordic citizen.
Have no criminal record.
