Can Americans use Uniswap?

Could you clarify for me whether Uniswap is accessible to Americans? I've been hearing a lot about this decentralized exchange lately and am interested in exploring its functionality. However, given the complexities surrounding cryptocurrency regulations in the US, I'm wondering if there are any restrictions or limitations that might prevent Americans from using Uniswap. Could you provide some insight into this matter? I'd appreciate any information you can share about the availability and usability of Uniswap for Americans.
