I Am An Heir On My Online Friend’s Will

I have been friends this guy for six months, he has helped me with some issues I was dealing with back then. We have been talking everyday for over six months and established a good friendship. He had a major accident on the first months of our friendship and he recently died. He is from America and I am from asia, we have never met in person and only interact through messages and calls. I am an heir on his will and will inherit an 8 digit amount from him. His nurses have told me and will later on connect me with his lawyers. Is this even legal and should I be worried about this? It would translate to over 10 digits in the currency of my country. Should I even receive it? It feels unreal to me and makes me worry of issues that may come along with it.
