Most people have the citizenship of their country of birth. Nevertheless, with worldwide mobility increasing, this is no longer necessarily the case. A British citizen could be born in India, while an Indian citizen in Britain. Currently, mainland China and Vietnam-born applicants are subject to visa retrogression. Therefore, a British citizen born in China would be subject to visa retrogression despite his/her British citizenship status. However, a Chinese citizen born in one of the Gulf countries such as the United Arab Emirates, Qatar, Bahrain, Kuwait, Oman, etc., would not be subject to it. That said, citizenship could affect whether the applicant could get a counselor interview after obtaining I-526 approval. For example, until recently, citizens of travel-ban countries such as North Korea, Venezuela, Syria, Somalia, Yemen, Iran, and Libya were barred from entering the United States.
