Software, Certification or License Needed to Land an Automation Engineer in the USA

Hi everyone,
I am an instrumentation and control engineer with 6 years' experience. Also a bachelor degree in Electrical Engineering from an ABET accredited university in my country.
I have a dream to land a job in the US. Hopefully in the near future.
Does anyone here knows what kind of software, certification and license should i pursue to get me to my aspiration?
In other words, what kind of resume that they wanna see?
Your help will be very appreciated.
