&gt; I wonder if there is any negative effects associated with being refused entry by a CBP? Could it be the case that if you are refused entry once, that in the future they will be more likely to refuse you entry? If so, that&#x27;s a fairly significant penalty&#x2F;power that the CBP person has.<p>Yes, some categories of non-citizen visitors (I don&#x27;t remember which) are asked on the form if they have ever been refused entry to the U.S. (and are required to answer yes or no).  If they&#x27;re using the same passport number as before, CBP likely also has access to a computerized record of the previous interaction.
