The former Dior creative director - who was sacked from the French fashion house after he was found guilty of anti-Semitic behaviour - had originally intended to complete a temporary residency with Oscar's label up until the autumn/winter 2013 show, which takes place tomorrow (12.02.13) and Oscar hopes he will stay on board with the brand.
He said: ''I would love for him to stay. Will he? I cannot tell you that today because we haven't gone that far in really discussing it.
''The fact is, we work very differently in New York than in Paris. It's night and day. We work at a much faster pace. So the answer is we don't know. We're still exploring.''
Although the 80-year-old designer admits he lacks common ground with John, Oscar appreciates the feedback from him and thinks he is extremely ''talented''.
He added to New York Magazine: ''I think the only similarity between me and John is that we both love what we do. I think that we're both learning from each other. I like hearing what he thinks should be changed and improved about each piece that we are showing in the fall collection.
''I think John is one of the most talented men I've ever met. I like him very much. I also believe that everyone should have a second chance, especially someone as talented as John. And he has worked so hard on his recovery.''
Supermodel Naomi Campbell has also expressed her support for John and describes him as a ''survivor''.
She said: ''You may take away his name, but you can't take away his talent. I've seen John, he's a survivor.
''He has nine lives. You have to forgive, everyone makes mistakes. I've been forgiven. I wouldn't be sitting here if I wasn't forgiven. We all are human.''
