Other important points to consider when intending to become a citizen of choice include the geographic location of the country, the official language, political and economic stability, the legal system, the banking and business environment, visa-free travel possibilities for passport holders of that country, the reputation of the country and the passport, and of course initial and future overall costs.
You will also need to consider restrictions on dual citizenship. Some countries do not allow you to hold any other citizenship besides theirs. About half of the world’s countries allow dual nationality, and the other half does not allow you to be a citizen of another country at the same time. Among those countries which do not allow dual nationality, various degrees of strictness can be observed, but often the acquisition of another citizenship without first obtaining a formal permission (which may or may not be obtainable) leads to the automatic loss of one’s current citizenship. Therefore, one needs to carefully check the legal situation in the home country with regard to dual citizenship, prior to taking any steps to acquire another citizenship.
The following is an overview of citizenship regulations in selected countries.38
Among others, the following countries allow the acquisition of another citizenship:
| Austria39 | Australia |
| Bangladesh | Barbados |
| Belgium | Belize |
| Brazil | Canada |
| Colombia | Croatia |
| Dominica | Cyprus |
| Egypt40 | Dominican Republic |
| Finland | El Salvador |
| Germany41 | France |
| Grenada | Greece |
| Iceland | Hungary |
| Iraq | Iran |
| Israel | Ireland |
| Jordan | Italy |
| Lebanon | Latvia |
| Macedonia | Lithuania |
| Mexico | Malta |
| New Zealand | Montenegro |
| Philippines | Pakistan42 |
| Serbia | Russia |
| Sri Lanka | Spain43 |
| St. Kitts and Nevis | St. Lucia |
| Switzerland | Sweden |
| United Kingdom | Syria |
| Vietnam | United States of America |
| Western Samoa |
On the other hand, countries which do not allow the acquisition of another citizenship include the following:
| Azerbaijan | Brunei |
| Chile | China |
| Czech Republic44 | Denmark |
| Ecuador | Fiji |
| India45 | Indonesia |
| Japan | Kazakhstan |
| Kenya | Kiribati |
| Kuwait | Malaysia |
| Mauritius | Myanmar |

One of the most important criteria specific to citizenship is of course the overall reputation of the country and its passport. It is futile to obtain a second passport if the country has a poor reputation at a regional and international level, and if therefore its passport is not well regarded and does not afford much visa-free travel.

20 This can happen even to citizens of small and generally neutral countries, as Danish citizens experienced following the publication of Mohammed cartoons in the Jyllands-Posten newspaper in Denmark on 30 September 2005
21 See Betten (1998) and the chapter in this book by Professor Langer on relinquishment of US citizenship
22 As an example, the Maltese Permanent Residence Scheme has been abruptly suspended by the Government in 2010, and following a review of the program new, stricter conditions and higher taxes were imposed
23 For example in St. Kitts and Nevis
24 Although some countries, such as the United Kingdom or New Zealand, have introduced limits to the passing on of citizenship infinitely through blood line
25 Some countries do not even allow you to give up your citizenship unless you have another one
