Where would you invest?

Hi, I got a question about where to put more money due to my current situation, I am an inmigrant (33yo) currently living here in USA, I got my brokerage account with Robinhood and my 401k and my roth IRA with fidelity, what could it be the best for someone in my case that I do not have a clear idea if I am staying here in USA or leaving to another country? what could it be the best for me in case that I need that money in the future? should I just put the minimun in 401k? max out roth? put more on robinhood? Just asking to try to find out where I could pay less money in taxes or fees in case that I need to withdraw the money because in moving out of USA?

I’ll cover this in tonight’s office hours (6/2/2021) with the recording available afterwards on the course site!
