inheritance

Hello, I'm a foreign national that works here in the US under a work visa and I pay taxes each year. My dad passed away on 2017 and we got an inheritance from him last year, I live and work in Missouri and I wonder if I have to report this to the IRS here. The inheritance are in a foreign account from the country we are from, so what implications would my situation have for my taxes last year?.. what would you recommend me to do?, thanks
