这是我打听到的提供签证服务的人的原话:From my experience very Few persons have been checked and when that has happened there is a process and they have gotten a special permit at the U.S. Immigration to go back into the U.S. and they pay a fee of $585.00 Dlls. To re-enter Into The U.S. 1 or 2 Months later they send You an e-mail or Call you to come and pick up your Visa. This process is the worst case Scenario.
