In a continuing effort to limit foreign immigration to the United States, the executive branch applies rigorous exclusion to immigrants who are liable to become public charges; potential immigrants need funds guaranteed to them by a sponsor already in the US. In 1930, 241,770 immigrants come to the US; after the imposition of consular restrictions, the numbers falls to 97, 139 in 1931, to 35,576 in 1932, and to 23,068 in 1933. The period of 1931-1936 are the years of the largest Jewish immigration to Palestine.
