As a child, Michelle Obama’s legal residence was in the British Virgin Islands. Her parents kept it that way so she would be eligible for immigrant status and special consideration for schooling.
Between birth and age 22, when she graduated college, Michelle Obama had only racked up two years of legal, US residency.
After college, in order to avoid paying taxes, she kept an address in the Cayman Islands from which she filed all of her tax returns. Therefore, none of the years between the time she graduated and the time she became First Lady count either.
While in the White House, the Obamas filed joint returns, giving her another seven years of residency. At nine years of residency, she is ineligible to be president.
She will qualify in 2021, meaning she will miss the next cycle and we won’t have to watch her campaign for the next four years.
