TR was also quite appalled by the situation, but as race relations and public education at the national/local level were regulated at the turn of the 20th century, its possibilities – even as president of the nation – were somewhat limited. When his request that the San Francisco school authority reconsider his plan fell on deaf ears, RT`s best bet was to challenge the settlement in court (barely a quick way to solve an international impact problem!). In a letter to a Japanese official, he explained that the U.S. government system made it difficult for the federal government to respond quickly to local statues. The gentlemen`s agreement of 1907 () was an informal agreement between the United States of America and the Empire of Japan紳協 which did not allow Japanese immigration and Japan to no longer emigrate to the United States. The aim was to ease tensions between the two Pacific states. The agreement was never ratified by the U.S. Congress and was replaced by the Immigration Act of 1924. Concessions were agreed in a note that, a year later, consisted of six points.
The agreement was followed by the admission of Japanese students to public schools. The adoption of the 1907 agreement spurred the arrival of “image marriages,” women who were closed remotely by photos.  The creation of distant marital ties allowed women who wanted to emigrate to the United States to obtain a passport, and Japanese workers in America were able to earn a partner of their own nationality.  As a result of this provision, which helped to reduce the gender gap in the Community, from a ratio of 7 men per woman in 1910 to less than 2 to 1 in 1920, japan`s population continued to grow despite the immigration restrictions imposed by the agreement. The gentlemen`s agreement was never enshrined in a law passed by the U.S. Congress, but it was an informal agreement between the United States and Japan, which was implemented by unilateral action by President Roosevelt. It was repealed by the Immigration Act of 1924, which prohibits all Asians from immigrating to the United States.  The treaty: an informal agreement between the governments of Japan and the United States that limited Japanese immigration to non-workers, workers already settled in the United States and their family members, that gentlemen`s agreements came to regulate international activities such as the coordination of monetary or trade policy.
 According to Edmund Osmasczyk in the United Nations Encyclopedia and International Agreements, it is also defined as “an international term for an oral and unwritten but fully valid agreement.”  This type of agreement may allow a nation to circumvent national legal requirements to enter into a formal contract or it may be useful for a government to want to enter into a secret agreement that does not engage the next government.  According to another author, all international agreements are gentlemen`s agreements because, just before the war, they are all unenforceable.  Osmaczyk noted that there was a difference between gentlemen`s open agreements and secret diplomatic agreements.  In the United States, in 1890, the prohibition of gentlemen`s agreements was introduced in interstate trade relations because the secrecy of these agreements was beyond anyone`s control.  An intense anti-Japanese atmosphere developed on the west coast.
