If you follow a tour group to the United States and escape, then you are staying in the United States illegally.

I'll tell you an open big secret. Regardless of police, immigration and national defense, there are millions of people living illegally in the United States. The police say only the bad guys are caught, and the simple definition is the person convicted by the judge. If they want to catch illegal immigrants, there are not so many prisons, and there are not so many idle meals. Immigration said that they issued visas to foreigners in accordance with government regulations. As for foreigners entering the United States, they have no "manpower" to follow up. They can't keep an eye on everyone. Every regiment went there and lived there. In recent years, the Department of Homeland Security and the Customs have received a lot of subsidies, but they only check. I have been in the United States for 30 years, and I have met many overstayers, but I have never seen anyone repatriated because of overstaying. Unless you break the law and the judge sentences you, Americans are unwilling to raise foreign prisoners in principle. The United States is vast and sparsely populated, and there are people in the metropolis on both sides of the strait. It often takes half an hour to drive inland to see a family. The United States always welcomes immigrants, but they want you to apply for naturalization in a proper way. However, most people don't follow the rules, including those who come to the United States for the first time. Aren't they all forced landings? If they can, we can't. It's a little unreasonable. Therefore, the U.S. government has always turned a blind eye to the overdue guests. For example, in my school, it is stipulated that if anyone with no identity asks to come to class, we will refuse, and we will put them in the "certificate group"-students with no identity. If we refuse to educate them, it is illegal for our school, especially for students below 17, and we must accept it. In fact, this has a humanitarian side. If you are dark and don't study, you will be forced to do evil. Many people work hard, study, start a business and get married as long as they don't break the law, and then apply for naturalization successfully when they have the opportunity to meet certain immigration regulations. Otherwise, the United States will grant amnesty every 20 years, and you can become a citizen at any time.
