Teammates and friends are concerned how Thon Maker might be affected by President Donald Trump's temporary ban on the entry of non-American citizens from seven Muslim-majority countries.
Maker was born in Wau, Sudan, which became part of an independent South Sudan in 2011. Sudan is one of the seven banned countries, along with Iran, Iraq, Libya, Somalia, Syria and Yemen.
Maker moved with his family to Australia in 2002, so he also has Australian citizenship and travels with an Australian passport.
There were concerns for Maker, however, as the Bucks were returning from a Friday night game in Toronto, just as U.S. Customs and Border Protection notified airlines about passengers whose visas had been canceled.
Luol Deng was also born in Wau, Sudan, but like Maker has dual citizenship, having become a British citizen in 2006.
Bucks senior vice president Alexander Lasry, whose father and Bucks owner Marc Lasry immigrated from Morocco, posted a series of messages on Twitter in support of Maker.
"I appreciate all the fans' concerns and prayers for Thon. And today, a Sudanese refugee who fled oppression and is an incredible young man will make his second NBA start," wrote Lasry. "I'm incredibly excited and proud of him. He's a symbol of what makes America great and all immigrants believe about America."
