In 1947, Henderson points out, only 2,382 natural scientists, engi- 

 neers, physicians, or surgeons immigrated to the United States. Data 

 on national origins are not available in existing records; however, it 

 can be assumed that since the immigration patterns then prevailing 

 were European-oriented, only a few hundred (possibly 300-400) at 

 most came from the LDCs. By 1965, "Immigrants with Occupations" 

 had increased twofold from the figure for 1947, but PTKs had nearly 

 tripled, increasing from 10,891 to 28,790, and moving from 16 per- 

 cent to 22 percent of all "Immigrants with Occupations." By 1968, 

 the PTKs had increased nearly fivefold, reaching a figure of 48,753 

 and constituting 23 percent of all "Immigrants with Occuptions." 

 In 1969, for the first time in recent years, they declined in num- 

 bers to 39,980. Among these PTKs, the engineers, scientists, and medi- 

 cal personnel by 1965 had reached 11,749, or almost a fivefold increase. 

 From this level, these categories increased to 11,449 in 1966, 20,760 

 in 1967, and 25,317 in the fiscal year ending June 30, 1968."^ 



A parallel trend in this rapid increase of professional immigration 

 is the even more rapid rate of increase in professionals entering from 

 the LDCs. (For a graphic illustration of this development, see Fig- 

 ures 1, 2 and 3. For statistical data on this matter, see Table 7.) Mr. 

 Henderson explains that from the 300-400 level assumed above for 

 1947, the immigration of professionals from the LDCs increased in the 

 following magnitude: to 2,231 in 1956 (about 25 percent of all 8,539 

 engineers, scientists, and medical personnel immigrating that year) ; 

 to 3,604 in 1965 (about 30 percent) ; to 5,440 in 1966 (about 40 per- 

 cent) ; to 10,254 in 1967 (50 percent) ; to 13,221 in 1968 (52 percent), 

 that is, numerically more than 33 times the estimated figure for 1947 

 and nearly 6 times the entrants for 1956. The trend towards increased 

 immigration of professionals from the LDCs, in Henderson's judg- 

 ment, was expected to continue.^^®
