The US then asked Poland to extradite Polanski in January 2015, but the country’s supreme court ruled in December 2016 that he had served his time under the plea deal.
Polanski wants to visit Tate’s grave in Los Angeles, the celebrity news website TMZ has reported.
Polanski was arrested in Switzerland in 2009 on a US extradition request and spent 10 months under house arrest before the Swiss authorities rejected the US order.
But in 1978, convinced a judge was going to scrap the plea deal and hand him a hefty prison sentence, he fled for France.
