Can immigrants enter and leave the United States while waiting for a green card after entering the country

Yes, no matter how you get your green card, you may be questioned by immigration officials and confiscated when you re-enter, which is the right given to them by American law.

Especially for those who hold green cards but don't live in the United States for a long time, such as some investment immigrants who still have business in China, if you leave the United States for more than six months, then you must have enough evidence to prove that you still keep in touch with the United States during this period, and you still have the will to live in the United States for a long time. Many immigration officers will seize the time to leave the United States and question whether you are willing to stay in the United States.

In addition, since Trump took office, he has signed a number of administrative orders, including demanding the expulsion of immigrants with major criminal records (whether illegal or legal), and the actions of the customs have indeed become stricter. Jason, an immigration expert in Nankai, pointed out that some of his clients with criminal records were directly confiscated by immigration customs officials recently.

Once the customs officers think you have a problem, they will ask you when you enter the country and decide to revoke your green card. They will ask you to sign a form, I-407, about agreeing to voluntarily give up your green card status. No matter what reason you are questioned, no matter whether you know English or not, never sign this form! Once signed, it means that you voluntarily give up your green card and will be repatriated immediately. There is no room for redemption.
