I had the privilege of knowing the late Andy Sundberg, the founder of American Citizens Abroad.

Sundberg was a key force in bringing about American legislation that made it easier for Americans abroad to transmit their US citizenship to their children. He founded the American Children’s Citizens Rights League in 1977.
Through American Citizens Abroad, which he founded in 1978, Sundberg was most recently involved in town hall meetings held in 2012 for Swiss-based American citizens concerned about new US tax reporting requirements such as the Foreign Account Tax Compliance Act (Fatca).
In an obituary published on Friday, GenevaLunch.com described Sundberg as one of the “staunchest defenders” of Americans overseas.
“His work, including thousands of letters sent to people in positions of influence, put him on a first-name basis with politicians, government leaders and celebrities, whether they agreed with him or were targeted by him as someone to be convinced of the need for change,” the obituary said.
Andy Sundberg was also a very staunch Democrat.
