White card refers to the information filled in in the United States, and the white card given by immigration officials to stay in the United States according to their personal visas and reasons for coming to the United States. The entry white card is an important identification document received by all foreigners when they enter the United States. ?
Since the white card is a document that controls how long a foreigner can stay in the United States at a time, it is best for every foreigner to keep a copy of the white card every time he enters the United States. These preserved white cards can be used as evidence of legal status in the United States. ?
In addition, because the white card indicates the individual's stay status and the time he can stay in the United States, it is best to check whether the identity on the white card and the time he can stay are accurate when receiving the white card given to you by the immigration officer. If in doubt, you can ask for correction on the spot. If it is not found in time, you can go to the immigration office of your place of residence to ask for correction under certain circumstances.
Unless the immigration officer indicates on the white card that you can't update or change your identity, you can usually apply to the immigration office to change your identity or extend your existing identity within the validity period indicated on the card without leaving the United States. Once the Immigration Bureau approves the application, it will issue another I-797 approval letter with a new white card. This new white card controls your status in the United States and how long you can stay. No matter how many white cards you have taken in the past, the last white card issued by the Immigration Bureau represents your current status in the United States and the duration of your stay.
In addition, if you don't receive this white card when you enter the United States, you'd better register and keep a record of each entry and exit (including date, entry and exit port, stay time, etc.). ) together with other evidence, such as the seal on the passport or boarding pass.
Although a card looks unremarkable, without it, it is likely to affect a person's life in the United States and even affect his application for a green card in the future. So be careful to keep it and copy it.
