The Raiders have officially begun the formal process of moving from Oakland to Vegas ... so says a Nevada official.
Clark County Commission chair Steve Sisolak tweeted out the news Thursday morning saying, "It is official! The @RAIDERS have filed their paperwork to relocate to #LasVegas."
Raiders owner Mark Davis has been exploring the move for years -- but really got the ball moving in 2016.
Unclear what the "paperwork" the team filed says ... but we're looking into it.
