Should I keep Trading 212 or move to IBKR?

Hello,
I am new to the stock investing and I have recently opened Trading 212.
The only problem is that I am a student in EU, and in a year and a half I will graduate and move out, either to the states or non-eu country.
I think that I can keep the bank account in Lithuania (Swedbank) even though I will not be a resident (I am a Romanian).

So what should I do?
Should I give up the Trading 212 and move to IBKR global? (mainly using s&p 500)
Unlike Trading 212, IBKR work in both the countries I am planing to move to after, don't know which one yet.

Thank you in advance.
