I am going to develop and write a long essay about this issue.It will be based on real life experiences from those who have succeeded in getting different types of visas to Sweden .Here are some questions i am going to answer:-
How they did it?
What steps did they take?
Why some people do not get it?
Certain things to avoid ?
How life in Sweden is sweet but also tough.
I hope this helps. For now just follow the information from Swedish immigration Just do as they say and follow the instructions they give you on the web site .Let your documents be right and let them be sent to the Swedish immigration authorities on time.
