No he didn't. He overstayed his Visa and y'all call those people illegal aliens.

“Since our initial fact-check in 2016, public interest in Musk's immigration status has persisted, particularly with the meme's resurgence in 2024. Updated sources further confirm that while Musk's immigration status may have been complex at certain points, and despite claims made by The Washington Post, no credible evidence supports that he was an "illegal immigrant," in his brother's words.

In sum, the claim that Elon Musk once held "illegal" status in the U.S. remains unproven. Musk's joke about being in a "gray area" hints at complexities but doesn't constitute evidence. Available evidence indicates he followed a legal path through student visas and H-1B temporary employment visas, allowing him and his brother to establish Zip2 in 1995. Musk later became a U.S. citizen in 2002, though the full details of his prior legal status remain partially unverified. There is no credible evidence that he was ever fully "illegal" during his more than three decades in the U.S.

We will continue to monitor this story for any additional documentation or insights into his early visa status, and we will update this article as more information becomes available.”
