Client Z is a Chinese citizen who is married to an American citizen, XX, and they have two American children. Later, his or her spouse submitted an IR1 spousal immigration application for him or her. The XX Consulate issued an IR1 visa, and Client Z entered the United States as a permanent resident in the same year. Client Z submitted an application for naturalization based on his spouse's overseas work in XX China, claiming that since his spouse is employed by an American multinational company and has been working in China for a long time, he will live overseas with his spouse and return to the United States after the employment period ends. The core dispute of the case lies in that the applicant joined the Communist Youth League of China due to the requirement of high school enrollment. The lawyer argued through a legal memorandum that the applicant's act of joining was involuntary, non-substantive and had exceeded ten years, and thus did not constitute an obstacle to naturalization.
