Will there be a problem if you don't receive the re-entry permit?

There is a problem. When the green card expires and it is suspected of illegal entry, it has not yet obtained the re-entry permit to enter the United States, which is problematic. American investment immigrant applicants with re-entry permit can return to the United States visa-free even if they have a long exit record. The United States of America (hereinafter referred to as the United States) is a federal constitutional country, which consists of Washington, D.C., 50 states, Guam and many other overseas territories.
