President Asiwaju Bola Ahmed Adekunle Tinubu was literally a US-migrated Nigerian, studying here for college and then working. Maybe you are not familiar with Nigeria, but a surprisingly large amount of those with legislative power have lived or held property in the US. You don't even have to "migrate" to buy property here, just show up, and you can leave (or do it remotely).

  Tinubu arrived in the United States in 1975, where he commenced undergraduate studies first at Richard J. Daley College in Chicago and then at Chicago State University where he majored in accounting and management. He worked odd jobs as a dishwasher, night security guard and cab driver to support himself through college.[13] He made the honor dean's list as an undergraduate and taught remedial class tutorials, some of his classmates credited his lectures for their improved grades. Tinubu was the university accounting society president in his senior year. His cumulative GPA was 3.54.[13] Tinubu graduated summa cum laude with a Bachelor of Science in Business Administration in 1979.[14][15]

  Early career
  After graduating, Tinubu worked as an accountant for the American companies Arthur Andersen, Deloitte and GTE Services Corporation.[16][17]
