I want to know the answer to the following question:
What program handled "essential aliens" that did not fall under normal immigration policies?
All the background I'm provided with is that "In 1949, Houston would help draft the Central Intelligence Agency Act, (Public law 81-110) which authorized the agency to use confidential fiscal and administrative procedures, and exempted it from most limitations on the use of Federal funds.". Is that enough to answer the question?
Answer: no
