I'm guessing that when King Michael was forced into exile in 1947, he probably thought he'd never set foot in his native land again. Thankfully, that was not the case. I wonder how many Monarchs the Communists forced out have gotten the chance to go back to their homelands after Communism was tossed into the gutter of history. Michael might be the only one to have done so, I mean he was alive when the Communist stole his country, and he lived to see their downfall (one wonders what he was thinking when Nicolae and Elena Ceausescu were dispatched to Hell as a Christmas gift), and he is still living now, part of the time in Romania.
None of the Romanovs that escaped Russia ever got to go back even for a visit, let alone live there (of course, the Communists were in power a lot longer in Russia than they were in Romania).
