A 59-item questionnaire covering all aspects of migrant labor was sent by the International Labor Office to member States, of whom 45 sent replies which are summarized in the document. For each of the questions, the question is reproduced and followed by a list indicating which governments responded and the nature of the response. The substance of selected responses is also reproduced. The replies are followed by short office commentaries. Proposed conclusions concerning migrant workers end the report and are intended to serve as a basis of discussion by the conference. Proposed international action covers the adoption of supplementary international instruments on migrant workers. These instruments should take the form of: (1) a convention on migrations in abusive conditions, (2) a convention on equality of opportunity and treatment, and (3) a recommendation on equality of opportunity and treatment (supplementary to the convention), on social policy, and on employment and residence in countries of immigration.
