According to TMZ, 21 isn't able to leave the country to perform until his issues with immigration are resolved, which could take years. The immigration courts in Atlanta are overwhelmed with cases. As for Savage, his case has yet to receive a court date. Because ATL's immigration offices are asking people to come to court in 2022, it is assumed there won't be a quick turnaround for Savage.
Following his release in February, 21 wasn't permitted to perform at any international or domestic shows. This sidelined the artist for eight months until he finally obtained a work visa in October. He's now allowed to tour the United States, which can help keep him afloat until he's free to cross borders.
The rapper is taking full advantage of his new visa. 21 Savage just stopped by ComplexCon Long Beach for an unannounced performance. The set caught visitors by surprise as they rallied to hear him perform a melody of hits. 21 ran through songs from Savage Mode, Issa Album, Without Warning, Not All Heroes Wear Capes, and i am > i was with ease. He even showed his core fan base some love by performing his breakout single "No Heart."
