OK BR here is why I persumed the law required you to give up citizenship of one to get the other. It used to be that way. The law was changed years ago. Also there is one thing you should check up on. All Male US Citizens are required by law to register with the selective service. Check their website, its says
Quote:DUAL NATIONALS
Dual nationals of the U.S. and another country are required to register, regardless of where they live, because they are U.S. nationals.
There are exceptions but if I were you I would verify if you need to do this. Service in one country's military does not automatically exempt registering in the US selective service data base. Check it out.

This is the info on why I thought you had to give up one for the other. The mere act of obtaining a citizenship in another country was cause for loss of US citizenship. Also the language in the oath of citizenship was construed to mean you gave up your other citizenship when the oath was taken. Also when I was stationed in England, many years ago, children of US service personnel born off base had dual citizenship until their 18th birthday and then chose one or the other. Now the law has changed.
The primary effect of recent developments in the US regarding dual citizenship has been to add the requirement that loss of citizenship can only result when the person in question intended to give up his citizenship. At one time, the mere performance of the above (or certain other) acts was enough to cause loss of US citizenship; however, the Supreme Court overturned this concept in the Afroyim and Terrazas cases, and Congress amended the law in 1986 to require that loss of citizenship would result only when a potentially "expatriating" (citizenship-losing) action was performed voluntarily and "with the intention of relinquishing United States nationality".
On 16 April 1990, the State Department adopted a new policy on dual citizenship, under which US citizens who perform one of the potentially expatriating acts listed above are normally presumed not to have done so with intent to give up US citizenship. Thus, the overwhelming majority of loss-of-citizenship cases nowadays will involve people who have explicitly indicated to US consular officials that they want to give up their US citizenship
