A related criterion is that the granting of citizenship and the passports issued in conjunction therewith have to be recognized by other countries. If full citizenship has been granted based on the legal provisions of a country, it will normally be recognized by other countries. However, if only non-citizens passports are granted, generally this is not a good option. One example is Panama where a (legal) non-citizens passport under the retiree residence program can be acquired.
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.46
Among others, the following countries allow the acquisition of another citizenship:
| Antigua and Barbuda | Australia |
| Austria47 | Bangladesh |
| Barbados | Belgium |
| Belize | Brazil |
| Bulgaria | Canada |
| Chile | Colombia |
| Croatia | Cyprus |
| Dominica | Dominican Republic |
| El Salvador | Egypt48 |
| Finland | France |
| Germany49 | Greece |
| Grenada | Hungary |
| Iceland | Iran |
| Iraq | Ireland |
| Israel | Italy |
| Jordan | Latvia |
| Lebanon | Lithuania |
| Macedonia | Malta |
| Mexico | Montenegro |
| New Zealand | Pakistan50 |
| Philippines | Romania |
| Russia | Serbia |
| Spain51 | Sri Lanka |
| St. Kitts and Nevis | St. Lucia |
| Sweden | Switzerland |
| Syria | United Kingdom |
| United States of America | Vietnam |
| Western Samoa |
On the other hand, countries which do not allow the acquisition of another citizenship include the following:
| Azerbaijan | Brunei |
| China | Czech Republic52 |
| Denmark | Ecuador |
| Fiji | India53 |
| Indonesia | Japan |
| Kazakhstan | Kenya |
| Kiribati | Kuwait |
| Malaysia | Mauritius |
| Myanmar | Nepal |
| Norway | Papua New Guinea |
| Peru | Poland |
| Portugal | Saudi Arabia54 |
| Solomon Islands | South Africa55 |
| Singapore | Turkey |
| Spain56 | Venezuela |
| Ukraine |
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 therefore its passport is not well regarded and does not afford much visa-free travel, or causes suspicion at international borders.

24 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

27 See Betten (1998) and Chapter 3 in this book
28 See Ong (1999)
29 For example in St. Kitts and Nevis
30 Although some countries, such as the UK and New Zealand, have introduced limits to the passing on of citizenship infinitely through blood line if not also remaining a resident
31 See Hokema (2002) and Hansen/Weil (2001) on multiple citizenship
32 Some countries do not even allow you to give up your citizenship unless you have another one. For a good discussion of statelessness, see Stiller (2011)
33 For example in China, Malaysia, the UAE and many other countries, there are minority groups which are resident there but are prevented from acquiring citizenship of the country they live in
34 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 of applying for Swiss citizenship. In some Asian countries, if you are not of a particular ethnic origin, your chances of ever being granted citizenship are close to zero. In most Muslim countries you need not apply if you are not Muslim

38 Henley & Partners constantly monitor and evaluate residence and citizenship programs around the world against a number of criteria
39 For an in-depth discussion of these options see Part IV
40 For example, Bulgaria, Cape Verde, Grenada, Nauru, the Seychelles, most South American countries, and others
41 Montenegro, for example, granted citizenship to the controversial former Thai Prime Minister Thaksin Shinawatra on the basis of a mere promise to invest in the country
42 Panama, under its retiree residence program
43 Tonga and a couple of African countries
