EU nationals working in other EU country have to overcome dozens of administrative obstacles to work in and fully integrate into to the other EU country - especially the different social security systems, different nature of the payment into these systems, registration to health care systems etc.

Therefore the EU should encourage the Member states to remove the administrative barriers to the Free movement of Workers through harmonisation of the social security systems and public healthcare systems, especially harmonisation of the the payments into these systems, sharing the information between the member states and securing the payments of the state pensions when citizen works in more EU countries.
