One of the most important criteria specific to citizenship is of course the overall reputation of the country and its passport.

22 Although some countries, such as the United Kingdom or New Zealand, have introduced limits to the ius sanguinis rule, i.e. the passing on of citizenship infinitely through blood line.

24 For example in the UAE, Malaysia, China and many other countries, there are many minority groups which are resident there but are prevented from acquiring citizenship of the country they live in
25 in some Swiss Cantons for example, you have to pass an “integration” test, which means that you may need to learn some Swiss history and other things deemed useful to qualify for the privilege to apply for Swiss citizenship. In some Asian countries, if you are not of that particular ethnic origin, your chances of ever being granted citizenship are close to zero

37 Persons may retain their former citizenship only if they apply to do so prior to taking out another citizenship (Beibehaltungsgenehmigung). Otherwise dual citizenship is generally not allowed, and if another citizenship is acquired Austrian citizenship is lost ex lege.

40 According to Chapter 14, Annex J-Article 6* of 1951 Pakistani Nationality Law and the amendments 1952, 1972, 1973 and 2000 stated that holding dual citizenship was not permitted.

41 Spain has dual citizenship treaties with Bolivia, Chile, Ecuador, Costa Rica, Guatemala, Nicaragua, Paraguay, Peru, the Dominican Republic, Argentina, and Honduras. Spanish citizens residing in these countries do not lose their citizenship if they adopt that citizenship. For all other countries, Spanish citizenship is revoked upon the acquisition of foreign citizenship.
42 In the case of the Czech Republic two specific exceptions apply. Most importantly in case of restoration of the Czech citizenship (while keeping the one possessed to date, for example U.S. citizenship) when the citizenship of former Czechoslovakia was illegally taken away between1948-1990 by the Communist regime or without losing the Slovak one
