Doesn't the American exit customs stamp?

When you leave the United States, your passport will not be stamped, and customs officials will not stamp you. I think many friends who often go to America must know this because there are certain rules and regulations. Let me explain it to you in detail.

Many domestic tourists are curious. When you leave the United States, your passport will not be stamped with your departure stamp. I looked it up on the internet, which means something like this.

Because there is a law in the United States that "everyone has the right to leave his own country", they will not stamp you when you leave the country. However, if you leave the United States by plane, the airline or airport will submit your information to CBP.

However, there is a wonderful question here. Last time I went to America, I drove from Los Angeles to Tijuana, Mexico. I drove all the way there without checking. Even if I left the United States, I didn't have an exit inspection. I entered Mexico, and there was no entry inspection in Mexico.

It takes about 2.5 hours to drive from Los Angeles to Tijuana, which means you can drive directly to Mexico, and when you drive from America to Mexico, no one will stop you from checking that place and driving all the time.

This is the scene before the Mexican port of entry:

After entering Mexico, it is actually the center of Tijuana, not far from the city center. Very close, obviously the speed limit on the road sign changed from miles to kilometers, and MPH changed to km/h.

Well, then, if you enter the United States from Mexico, you will have a headache. You have to wait in line for a whole afternoon, four and a half hours, and the long queues are checked one by one. Whether you leave Mexico or not means that no one will check my passport when I enter Mexico or even leave Mexico. Only I re-entered the United States, and the United States unilaterally inspected. Maybe it's really the first world and the third world. Everyone knows that people vote with their feet.

The queue is particularly long, and the middle of the road is full of vendors who keep selling goods.

It is the port in front of the United States, that is, the legendary San Isidro Port, where the caravan of illegal immigrants from Central America will meet. However, there seems to be no caravan on the road, and it is estimated that it has long been expelled and intercepted.

At this port of entry in the United States, people don't have to get off the bus, and CBP police patrol around with police dogs. Sometimes, they worry that the police dog's nose is not broken, and barking a few times may cause big trouble and may have to check the whole car. When crossing the port, you will be asked where you live in the United States, whether you have shopped in Mexico and so on. Then I will check whether your passport is consistent with the person and enter the country directly.

For immigration records in the United States, you can check the I94 records on CBP's website.

For example, this is the case when I check my own records. There are two entry records, one at LAX Airport in Los Angeles, the other at SYS (San Isidro), and then there is a departure record, which creates asymmetry.

Sometimes I have a question. For example, if I ask an American to send me to Mexico, and then I fly back to China in Mexico, will Mexico think that I have entered the country illegally? The United States doesn't know that I have been to Mexico, and even thinks that I have been to the United States and there will be a detention record.

Actually, don't worry. The official explanation is this. Many domestic travel websites can't find a correct and complete explanation.

What does it say? Let me sum it up. For example, if you drive to Mexico, you can print the i94 form and give it to the relevant officials (in the United States or Mexico). If you fly to Mexico, save your subway ticket generated in Mexico, or your departure stamp or air ticket, so that the next time you enter the United States, you can prove that you left the United States on those dates.

In addition, the immigration authorities in the United States have contacts with those in Mexico and Canada. The United States is called CBP, Canada is called CBSA, and Mexico is called INM.

Or if, like me, you just went to Mexico from the United States and re-entered, then your validity will be counted from the date of your first entry.

If the United States really wants to go to Mexico, or Mexico wants to go to a third country and fly around, as long as you keep the relevant official evidence such as air tickets and subway tickets, you can make it clear when you enter the country next time that you leave the country by land.
