My Mum lives in the US, at her age (60) she earns a decent living working in a home, she has even added a few medical certifications to her CV and is still going for more certifications how much more a youngie like you that is brilliant, resilient and hardworking.
What you are afraid of in the US, we have it @ its peak here in Nigeria so please don't waste this opportunity to explore.
All the best in whatever decision you make and keep us posted.
