Applicants must be in the United States to apply for a green card. Although there is no need to provide evidence of the person in the United States when applying, relevant evidence, such as I-94 form, passport and visa copy, should be kept for immigration verification. Because people can only apply for a green card in the United States, separated couples generally cannot apply at the same time. For example, the husband works in the United States and applies for a green card through professional immigration, while the wife still lives outside the United States. A wife cannot apply at the same time as her husband. In this case, the husband should apply for the so-called I-824 immediately after obtaining the green card, that is, ask the relevant immigration department that approved his green card to inform the American overseas consulate to allow his wife to reunite with her husband as a green card. If the husband applies for a green card to the regional center of the US Immigration Service, the center will directly approve his green card, and the husband should immediately send the application to I-824. If the center transfers its green card application to the local immigration office, the husband should apply for I-824 immediately during the interview, which can save a lot of time. It should be noted that the husband and wife get married first, and the husband gets a green card later. In this case, the wife doesn't have to wait a long time to apply for a green card according to the so-called timetable. From the legal point of view, if the husband gets married after getting a green card and puts forward the so-called second priority application for relative immigration, it will take a long time to get a green card after getting married. The application is for the reunion of husband and wife (with
