Soraya’s uncle has lived in the United States for over twenty years and works for the Immigration and Naturalization Service (INS). He helps Amir secure Sohrab’s entry into the United States.
Circumstances force Amir to go to Afghanistan to rescue his nephew Sohrab, Hassan's only child. He manages to track the boy down and finds the boy under Assef’s custody. After a brutal fight with Assef, Amir and Sohrab manage to escape. In order to ensure Sohrab’s safety, Amir and Soraya decide to adopt the boy and bring him to America. However, the adoption and subsequent visa process are challenged by the INS. Sharif steps in and makes some calls to friends at the INS. He later informs Soraya that their best bet is to get Sohrab to the United States under a humanitarian visa then make an adoption petition. Sharif also adds that he is in a position to help Sohrab secure the humanitarian visa, which is a relief for Amir.
At the end of Chapter 24, Amir receives a phone call from Soraya telling him that her uncle Sharif said that the key to adopting Sohrab was to get him into America first. Once Amir is able to get Sohrab into the United States, there are ways to keep him in America. Sarif has acquaintances that work for the Immigration and Naturalization Service (INS), and he said that he was almost certain that he could get Sohrab a humanitarian visa. A humanitarian visa is granted to those individuals who are unable to enter the United States but need to do so on a temporary basis because of a compelling emergency. Sarif's option is appropriate, and Amir is elated to learn that there is a way to get Sohrab into America. Unfortunately, Sohrab attempts suicide in the bathroom while Amir is on the phone receiving the good news.
Soraya's uncle works for the Immigration and Naturalization Service (INS) and is therefore able to facilitate the transfer of Sohrab from the Middle East to San Francisco. His efforts serve as the final recourse for Amir since adoption is not feasible because he cannot prove that the child's parents' have died.
