"In 2002, security into the U.S. got so tight that I panicked and became a citizen. It's been downhill ever since."
Dr. D was a Brit who moved to the U.S. after finishing his PhD. He took a job at my university, where he met, fell in love with, and married a girl from Iowa. They have two girls.
After 9/11, he was terrified that he would make a trip to the U.K. to visit his parents and then not be able to re-enter the U.S. The thought of being separated from his wife and children terrified him so much that he became a citizen.
Now that he's divorced, I wonder if he feels like becoming a citizen is just another thing to add to his list of regrets.
