Qualitative data on citizenship regulations and policies are today essential for orienting public debates and policy making. Yet such data are not easy to find and collecting systematic and reliable information for comparative purposes (both cross-time and cross-section) poses formidable challenges. The EUDO CITIZENSHIP observatory has been able to fill this gap and has thus established itself as a unique and highly appreciated tool for researchers and policy-makers alike. In addition to my colleagues and students I have signalled the EUDO website to various private research institutions and journalists interested in migration, residence laws and "conditional" citizenship and I can testify that they now regularly navigate the site and use it for policy papers and news articles. EUDO is a tremendous intellectual achievement, a benchmark for how to build an easily accessible, yet reliable and precise online source of relevant data.

How many web-places can attract at one and the same time migrants wanting to figure out the rules of the game as well academics working on comparative law, historians, lawyers, political scientists, journalists, bureaucrats and politicians! The EUDO CITIZENSHIP website is unique in combining extremely extensive and up to date data on citizenship in the EU, intelligent and clear-eyed analysis of all legal and political aspects of citizenship and breaking news on the subject. At last, the issue of trans-European citizenship has truly come alive fo the benefit of us all.

The EUDO CITZENSHIP Web site staff are to be greatly commended for marshalling in one place a comprehensive array of legal, analytical, and statistical information on citizenship in EU countries from the continent’s top experts. This is an important compendium, one that without question should be the first place policymakers, researchers, and journalists with questions about citizenship and nationality laws visit. From our experience, we know the value of presenting hard-to-find migration data and analysis online – and keeping it current. EUDO has made an important contribution for those interested in migration matters.
"The EUDO website on citizenship is a remarkable intellectual resource. It is the first place to which I direct colleagues and students interested in questions about citizenship and immigration in Europe today. It provides not only basic, up-to date information about laws, policies, and empirical developments but also stimulating analyses and discussions. This is a major contribution to public discourse"

"The Citizenship Observatory is a formidable research tool. It enables the field to move from an excess of abstract conceptualizations to research rooted in detailed legal practice. European Citizenship is meant to be complementary to Member State nationality. The one cannot be studied or understood without the other. Now the resource exists to realize that imperative."
