You can still vote - the idea is you are a US Citizen.
Your voting residence is your address in the State in which you were last domiciled, immediately prior to leaving the United States.
This residence may remain valid even if:
You no longer own property or have other ties to that State.
Your intent to return to that State is uncertain.
Your previous address is no longer a recognized residential address.
Even those we are US Citizens who never lived in the US can vote depending on the state that their parent(s) last resided.
