US Embassy in London, UK

Getting into a situation where you need the services of your embassy during a trip can be really stressful – although it’s decidedly less so if you can speak the language. And no matter what you think about American English vs. England English, the fact remains that finding your way to the U.S. Embassy in London is going to be easier because you already speak English.

It’s important to note here, however, that the Embassy’s mailing address and physical address – however similar they may look – are different. If you plug the mailing address into Google maps and rely on that location you’ll be directed to a post office in London. Make sure you’re using the post code from the physical address listed below instead.

Here’s the information you’ll need to contact or get to the U.S. Embassy in London, UK.
