I recently became a naturalized citizen of the United States, age 57. My mother passed away several years ago, and my father has been living with his brother in our home country, China, ever since. The two of them are getting elderly, and they take good care of each other. I would like to bring my father to the U.S. so that I can help care for him, and can spend time with him in his last years. However, I worry about what will happen to both him and my uncle if the two of them are separated. Is there any way I can petition for my uncle to immigrate as well?
