The question is, did he ever legally immigrate. I’ve seen nothing that proves he did.
“The billionaire South African-born immigrant also admitted in an email that he ‘had no legal right to stay in the country’ when he ditched his studies and founded a company which he later sold for more than $300 million, The Washington Post reported. His brother was also here illegally, committing what one expert called ‘fraud upon entry.’”

One more thing since I’m talking aloud Musk’s problem with the TRUTH: he didn’t found Tesla:
“Tesla was founded in July 2003 by Martin Eberhard and Marc Tarpenning as Tesla Motors.”
“Eberhard filed suit against the luxury electric vehicle maker in June, alleging that current CEO Elon Musk sought to "rewrite history" about Eberhard's role after Eberhard was ousted from the CEO position.”
Yeah, Musk doesn’t like history or truth.
