Tristan Thompson has a lot to celebrate this month.

The Canadian-born NBA star, who recently joined the Boston Celtics, became an American citizen this week, according to a photo shared by the US Citizenship and Immigration Services-Western Region Twitter account.

“I came to the US on a student visa and have always had big dreams. I’m now truly living the American dream,” Thompson said in a statement.

Thompson, 29, attended the University of Texas and declared for the NBA Draft in 2011. He was selected fourth overall by the Cleveland Cavaliers that year.

Earlier this month, it was reported Thompson had agreed to a two-year, $19 million deal with the Celtics after nine seasons in Cleveland. In response to the news, Thompson received a flurry of well-wishes on social media from Khloé Kardashian’s family.

“Congrats @realtristan13 Boston here we come!!!!” Kim Kardashian posted to her Instagram story at the time.

“LET’S GO @realtristan13,” Rob Kardashian also shared on his Instagram account.

Thompson shares 2-year-old daughter True with Kardashian, 36, who also received a warm welcome from Celtics fans on Twitter.

Thompson and Kardashian previously split in February 2019 after he was accused of cheating with Jordyn Woods. Over the summer, Thompson and Kardashian fueled reconciliation rumors.
