Have an Answer?
Let's first start with what have you been doing for the last 10 years and what are your interests and hobbies? In US, one good thing is that if you try hard enough, generally you can find a job or grow a career in anything and any fields. The hard advice for you is really around that unlike others who are raised in US, you lost around 15 years of time so restarting now is more a reset and not restarting from the beginning. Time is your worst enemy and you cannot turn it back. Go with what you like and have done in the past; leverage as much as possible. Maybe that is a shorter path to get a career going here in US.
Do you have current knowledge/experience that you wish to build upon or do you wish to transition to a different career?
The question you ask is very broad and a lot depends on what your long term goals are, your inherent capabilities and skills are and your personal visa/family situation.
So a common answer may be difficult to provide.
However, if you want to see the best careers based on various criteria there are some online resources available:
I'm sure there are others that you can come across using your fav search engine.
Hope this helps.
