The RFSL describes current guidelines as "inconsistent" and "unsafe", Swedish daily Svenska Dagbladet reports.
The RFSL has published two reports, the first of their kind, that look at the decisions handed down by the Migration Board regarding asylum seekers' applications from Nigeria and Uganda - two countries where LGBT individuals face the risk of severe discrimination.
Forty-one of the 44 Nigerian LGBT asylum applications reviewed by the Board between January 2010 and April 2013 were rejected. Fifty of the 58 applications from Ugandan asylum seekers were rejected in the same period.
The author of the reports, Stig-Åke Petersson, says that the Migration Board currently tends to disregard whether a person is gay and therefore fails correctly to assess the risks involved for people to return to these countries.
