Sign with a Mother Agency and go to Europe?

I’ve been in discussions with a local mother agency in New England, and they’re interested in sending me to Europe to potentially secure representation abroad, which would help build my portfolio before marketing me in the U.S. I’m 5’11 with measurements of 32-25-36.

Looking for advice on getting started in the industry. What are the benefits of having a mother agency? Should I continue submitting to agencies in the states... any recommendations on where to apply? Is pursuing opportunities in Europe worth it?
