Doesn't the American exit customs stamp?

When the United States leaves the country, the passport will not be stamped, and the customs officers will not stamp you. Presumably, many friends who frequent the United States must know this, because there are certain rules and regulations. Let me explain it to you in detail.

Many tourists from China are curious. When they leave the United States, their passports will not be stamped with departure stamps. I searched online, and it probably means something like this.

Because American legislation stipulates that "everyone has the right to leave his own country", they won't stamp you when you leave the country, but if you leave the country by plane, the airline or airport will submit your information to CBP.

But there is a strange problem here, that is, the last time I went to the United States, I drove from Los Angeles to Tijuana, Mexico, and I didn't check all the way. Even if I left the United States, I didn't check out. When I entered Mexico, Mexico didn't check out.

It takes about 2.5 hours to drive from Los Angeles to Tijuana, which means you can drive directly to Mexico and from the United States to Mexico without anyone stopping you to check.

The front is the appearance of the Mexican port of entry:

After entering Mexico, it is actually downtown Tijuana, and it is not far from the city center. It is very close, and it is obvious that the speed limit on the road sign has changed from miles to kilometers, and MPH has changed to km/h.

Well, then, if you enter the United States from Mexico, it will be a headache. There was a long queue for four and a half hours, and one car after another had to be inspected. Whether you leave Mexico or not, it means that no one checked my passport and documents when I entered Mexico or even left Mexico. Only when I enter the United States again will the United States unilaterally investigate, perhaps it is really the first world and the third world. As we all know, people vote with their feet.

It's a long line, and the middle of the road is full of vendors who keep selling goods.

Ahead is the American port, the legendary San Isidro port, where caravans of illegal immigrants from Central America will hit, but there seems to be no caravan on the road, so it is estimated that they have been expelled and intercepted long ago.

At this American port of entry, people don't have to get off. There are CBP police patrolling around with police dogs. Sometimes they worry that the police dog's nose will be broken and they will bark a few times. Then it may be in big trouble, and it may be necessary to check the whole car. When crossing the port, I will ask you where you live in the United States, whether you have done any shopping in Mexico, and then check whether your passport matches the person and enter the country directly.

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

For example, I checked my records. There are two entry records, one at LAX airport, one at SYS (San Isidro) and one at departure, 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 went to Mexico, and even thinks that I have been staying in the United States. Will there be a detention record?

Actually, there is no need to worry. The official explanation is this. Many domestic travel websites cannot find a correct and complete explanation.

Let me summarize what is mentioned in it. For example, if you drive to Mexico, you can print the i94 form and give it to the relevant officials (whether in the United States or Mexico). If you fly to Mexico, keep your subway ticket, departure stamp or plane ticket generated in Mexico, so that you can prove that you left the United States on those dates when you enter the United States next time.

In addition, the entry-exit administrations of the United States, Mexico and Canada are connected. 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 residence is still valid from the day you first entered.

If you really want the United States to go to Mexico, or Mexico to go to a third country and fly around again, you only need to keep the relevant official evidence such as air tickets and subway tickets, and you can explain clearly that you left the country by land when you enter the country next time.
