Sampson, 25, has been unveiled at the ambitious second-division American club based in Albuquerque, which has set their sights on the MLS.
"I’ve never learnt to give in, with God all things are possible. Can’t wait to get started with this special group of players we have,” Sampson told the club's website upon his unveiling.
"Looking forward for the journey with our fans and players. Thank you, New Mexico, for this opportunity."
Comfortable at right-back or in central defence, Sampson who hails from Mitchell's Plain in Cape Town departs the borders once again after a short stint with Ubuntu FC in the National First Division.
The academy graduated of the defunct African Soccer Development Academy played alongside Ebrahim Seedat of Cape Town City and South Africa international playmaker Ayanda Patosi before joining MLS side Vancouver Whitecaps back in 2013.
He also represented South Africa at U17 and U20 level.
