How does this dual citizenship work? Can one individual hold the passport of two countries? I thought that was illegal.
It used to be illegal but several court decisions have made it legal.These decisions have made it next to impossible for one to lose his/her US citizenship without actually renouncing it.
With the exception of US/Israeli dual citizenship, our State Department does not officially recognize the concept. It’s not illegal, however, because of the 1967 SCOTUS ruling. As a practical matter, if you hold two passports you have to be careful which one you use when entering a country. If, for example, you hold both a US and an Italian passport and you use the Italian passport to enter Germany and you then get in trouble with the German legal authorities you can’t count on the US embassy to help you out.
It’s also nonsense to say, as did one person in the article, that with US citizenship you can only work in one country (the US). Whether or not you can work legally in a foreign country depends on what kind of visa you enter with. For example, at different times I have worked legally in France and in the UK.
Yes,one can have as many passports as they can qualify for under the citizenship laws of the countries involved.Most western countries (but not all) allow dual/multiple citizenships.Third World-type countries tend not to allow it.
