The USA Visa Authorization System, performs checks against law enforcement databases. All travelers seeking admission to the United States are required to obtain the necessary authorization prior to being granted boarding.
If your Visa travel authorization application is approved, it establishes that you are eligible to travel, but does not establish that you are admissible to the United States. Upon arrival to the United States, you will be inspected by a Border Officer at a port of entry who may determine that you are inadmissible for any reason under United States law.
All information provided by you, or on your behalf by a designated third party, must be true and correct. A visa may be revoked at any time and for any reason, such as new information influencing eligibility. You may be subject to administrative or criminal penalties if you knowingly and willfully make a materially false, fictitious, or fraudulent statement or representation in an online visa application submitted by you or on your behalf.
