I've personally no problem to understand you.
English is the main language for it...
But it could have been very different if France haven't sold a part of the territory to the US(the Louisiana,which was way bigger than the actual state),centuries ago,the US may have spoken french,and it would have changed a lot of things about international discussion...
I had troubles to try to learn spanish too.
You're still understandable,don't worry.
You can try to use translator to help you if needed.
