66 Copenhagen 1990 (19.1) - strive to implement the procedures for entry into their territories, including the issuing of visas and passport and customs control, in good faith and without unjustified delay. Where necessary, they will shorten the waiting time for visa decisions, as well as simplify practices and reduce administrative requirements for visa applications; (19.2) - ensure, in dealing with visa applications, that these are processed as expeditiously as possible in order, inter alia, to take due account of important family, personal or professional considerations, especially in cases of an urgent, humanitarian nature; (19.3) - endeavour, where necessary, to reduce fees charged in connection with visa applications to the lowest possible level. (20) The participating States concerned will consult and, where appropriate, cooperate in dealing with problems that might emerge as a result of the increased movement of persons. (…) (22) The participating States reaffirm that the protection and promotion of the rights of migrant workers have their human dimension. In this context, they (22.1) - agree that the protection and promotion of the rights of migrant workers are the concern of all participating States and that as such they should be addressed within the CSCE process; (22.2) - reaffirm their commitment to implement fully in their domestic legislation the rights of migrant workers provided for in international agreements to which they are parties; (22.3) - consider that, in future international instruments concerning the rights of migrant workers, they should take into account the fact that this issue is of importance for all of them; (22.4) - express their readiness to examine, at future CSCE meetings, the relevant aspects of the further promotion of the rights of migrant workers and their families. (23) The participating States reaffirm their conviction expressed in the Vienna Concluding Document that the promotion of economic, social and cultural rights as well as of civil and political rights is of paramount importance for human dignity and for the attainment of the legitimate aspirations of every individual. They also reaffirm their commitment taken in the Document of the Bonn Conference on Economic Co-operation in Europe to the promotion of social justice and the improvement of living and working conditions. In the context of continuing their efforts with a view to achieving progressively the full realization of economic, social and cultural rights by all appropriate means, they will pay special attention to problems in the areas of employment, housing, social security, health, education and culture. (24) The participating States will ensure that the exercise of all the human rights and fundamental freedoms set out above will not be subject to any restrictions except those which are provided by law and are consistent with their obligations under international law, in particular the International Covenant on Civil and Political Rights, and with their international commitments, in particular the Universal Declaration of Human Rights. These restrictions have the character of exceptions. The participating States will ensure that these restrictions are not abused and are not applied in an arbitrary manner, but in such a way that the effective exercise of these rights is ensured. Any restriction on rights and freedoms must, in a democratic society, relate to one of the objectives of the applicable law and be strictly proportionate to the aim of that law.
