Like others have already pointed out your challenge is not only your accent. If you tackle it as language ackquisition there is a large community for adults learning languages. Working in the US gives you a big advantage but immersion alone will not automatically solve all issues.
In my experience you can benefit from language tandems. In this setup one has a conversation with a native speaker who learns your native language. Half of the time you speak your native language, the other half his/her native language. In this setup it is not as awkward to correct each other as it is in daily life conversations. Tandems can be online or in person. If you want to maximize your time speaking and being corrected you can pay some students to act as a teacher. I had some really good experiences while learning Italian on italki.com. Just look for community teacher. Unfortunately they no longer support forming tandems. But there are plenty of sites for this.
