Can I enter America with a blank passport?

Qingdao English Private School answers for you: hold a passport, and then the passport has an entry visa for the country you want to go to, so you can buy a plane ticket to the country you want to go to, the United States. When you board the plane, you board the plane from the airport in China. Because you are on an international flight, you must go through the exit formalities in China. Yes, there will be another China exit stamp on your passport. When you arrive in the United States, you must go through the immigration formalities in the United States at the airport. At this time, officials of the US Immigration Bureau will check your passport, the US entry visa stamped by the US Consulate in China and the exit stamp of China Customs. Everything is all right, and then ask a few questions, such as what is the purpose of coming to America? How long are you going to stay? Then, wait a minute, put an American entry stamp on your passport. After that, you will set foot on American soil. According to your question, I think you are talking about the exit stamp of China. When you leave China, your passport must be stamped with the departure stamp at the airport customs in China, and then American airport immigration officials will let you enter the United States. Without this seal, you will be in trouble when you enter the country. So when you enter the United States, your passport must be stamped with at least three stamps, and then the immigration officer at the American airport will stamp you with the fourth stamp, and you will be OK. I repeat: a valid China passport, a valid entry visa from the US Consulate in China, a departure stamp from China Customs and an entry stamp from the US Immigration Service.
