In the latter half of the 19th century, the principle role that New York City filled for Mormonism was as a transit point—more than 75,000 Mormon converts entered the United States through New York City during those years while several thousand missionaries sailed for Europe from New York’s port. But beginning with the Page Act in 1875 and the Chinese Exclusion Act of 1882, the U.S. began restricting immigration, beginning with Chinese and also including convicts, lunatics, and “others unable to care for themselves.” And in the late 1880s, attention on polygamy prosecution in Utah led to a provision of the Geary Act of 1892 which prohibited entry by polygamists. If you were restricted from immigrating, you were sent back.
A High Priest I know is in crisis. He is an immigrant who, like many other Church members, came to the US without a visa, according to what I understand of the situation. After arriving here he joined the Church, and eventually fell in love and married a U.S. Citizen, a wonderful, faithful Church member. This situation would normally put him on track for a green card and U.S. citizenship. But this brother is facing deportation, and his ward and stake are praying for a miracle that will keep him here in the United States.
