1. It looks likely he was here illegally

He was here on a J-1 student visa:

"... Musk arrived in Palo Alto in 1995 for a graduate degree program at Stanford University but never enrolled in courses. Instead, he launched a start-up, Zip2, that later sold for about $300 million. ... Leaving school left Musk without a legal basis to remain in the United States, according to immigration experts — a fact that was discovered by Zip2 investors, who gave Musk and his co-founders 45 days to obtain legal work status."
