There are some gotchas. The US doesn’t acknowledge dual citizenship, and I believe you must travel in/out of the US with a US passport. If you have a US security clearance or wish to obtain one, you will have a problem as well.

From my understanding the US just pretends that you are only a US citizen. Which doesn't sound like a problem.
This is true for every country I've heard of (if you hold citizenship for that country you're supposed to use that passport)
How is that a gotcha?
There may be others — citizenship is a deeper commitment than a visa.
Post-2017 new guidance proclaimed that confiscated passports should be returned immediately, and this language was added:
> By itself, the fact that a U.S. citizen is also a citizen of another country is not disqualifying without an objective showing of such conflict or attempt at concealment. The same is true for a U.S. citizen’s exercise of any right or privilege of foreign citizenship and any action to acquire or obtain recognition of a foreign citizenship.
So generally speaking, it's not a disqualifying event to hold dual citizenship, so long as the foreign country is not "at conflict" with the US and some other conditions are met.
I'm not an expert, but this is my understanding of the current status.
