The investigation will look at significance of Swedish citizenship and, if needed, how that can be legislated.
It will also suggest what a ceremony for all new Swedish citizens might look like. Ullenhag refers to the use of such ceremonies in Canada, the U.S. and Australia, countries which he believes have been successful with immigration.
At a press conference, Ullenhag said the investigation will also look into the requirements of becoming a Swedish citizen, for example, the length of time one needs to reside in Sweden to become one. He did not rule out the possibility of a language test.
