What if I enter the United States without an entry stamp on my passport?

The measures to enter the US Customs without a stamp are as follows: If you have arrived at the Customs, but find that your passport is not stamped, you can make up the stamp at the entry-exit checkpoint in time. Generally, there will be a "stamp adding place" at the customs checkpoint, and you can print on this machine yourself. What everyone should remember is that after entering the country through the self-service channel, it is best to print the "entry certificate" with this machine. And you need to take good care of yourself, which is an important proof that you have passed the customs. If passengers don't find their passports stamped when they are about to pass the security check, they can go back to the airport entry-exit permit office to contact the staff, and remember to keep the tickets, boarding passes and other materials that can prove the entry time, and go to the customs entry-exit permit office to make up the stamp. As long as you can successfully pass the self-service customs clearance, you won't encounter problems when you leave the country. 2. Issues needing attention in entry and exit: 1. Visitors who want to go abroad should check their passports as soon as they enter the country to see if they are stamped. Or you have already applied for a replacement card, but forgot to get the entry permit. At this time, you can go to the immigration office to get a new license. 2. If it is stamped, everyone should check whether their passports are stamped with the entry stamp and whether the date on the entry stamp is correct. 3. Self-service customs clearance systems are set up at the entry-exit checkpoints in China, but for those friends who forget to stamp, remember to take the manual passage and stamp their passports with entry stamps.
