You're in your 30's. Take a long term, and not short term, view of the future. Are you better off staying overseas? Or would getting your 4 yr degree in the U.S. while you're at a regional airline flying 121 flying be a better long term option? With no four year degree, no 121 time, and thinking that you could go from Captain overseas to Captain in the U.S., you need to research what the criteria and typical resume of U.S. new hires are.
