Answer:
Beginning in the 1880s, an era of qualitative immigration restrictions began as certain types of immigrants were barred: prostitutes, workers with contracts that tied them to a particular employer for several years, and Chinese. In the 1920s, quantitative restrictions or quotas set a ceiling on the number of immigrants accepted each year.2
Immigration law changed in 1965. Qualitative and quantitative restrictions were maintained, but national origin preferences that favored the entry of Europeans were dropped. U.S. immigration policy began to favor the entry of foreigners who had U.S. relatives and foreigners requested by U.S. employers. During the 1970s, the origins of most immigrants changed from Europe to Latin America and Asia: U.S. immigration has occurred in waves, with peaks followed by troughs (see figure). The first wave of immigrants, mostly English-speakers from the British Isles, arrived before records were kept beginning in 1820. The second wave, dominated by Irish and German Catholics in the 1840s and 1850s, challenged the dominance of the Protestant church and led to a backlash against Catholics, defused only when the Civil War practically stopped immigration in the 1860s.
The third wave, between 1880 and 1914, brought over 20 million European immigrants to the United States, an average of 650,000 a year at a time when the United States had 75 million residents. Most southern and eastern European immigrants arriving via New York’s Ellis Island found factory jobs in Northeastern and Midwestern cities. Third-wave European immigration was slowed first by World War I and then by numerical quotas in the 1920s.

Hunger refers to the periods when people are experiencing severe food insecurity, that is, they do not eat food for days at a go due to lack of money, lack of access to food or other important resources, as stated by the UN's Hunger Report.
Usually we associate the term hunger with lack of food. The threshold for undernourishment happens to be 1800 calories a day. Undernutrition may not just be because of lack of calories, but also because of the deficiency in energy protein or vitamins or other essential minerals.
Food security crisis can be sometimes because of food unavailability or no access to it.
