You will keep your u.s. nationality. you may,in time attain another nationality
and become a dual national.
good luck

 

Marrying another national does not make you lose your US citizenship. There are certain countries that the US will not allow you to have dual citizenship with, and vice versa, some countries may not allow you to have dual citizenship with the US, mostly they are politically motivated. But if you marry a UK National, from what I've read, you can hold dual citizenships from the US and UK.

 

Re: Thanks re: US marrying UK or EU citizen

If you're a U.S. citizen, you won't lose your U.S. citizenship by marrying a citizen of any other country. You also won't lose your U.S. citizenship if you later become the citizen of another country...as long as you don't specifically intend to renounce your U.S. citizenship. Some countries do not permit their citizens to become citizens of other countries and retain their original citizenship, but many countries these days (U.S., Canada, U.K., Italy) don't object to multiple citizenships. Here's a list of all the countries and their stands on dual citizenship: http://www.multiplecitizenship.com/worldsummary.html
