Many travelers with a DUI infraction attest to having no difficulty crossing the border for a visit while others have been turned away and refused entry. All of the following factors may come into play at the point of entry:
(1) The severity of the infraction: If the offence was prosecuted as a misdemeanor, it is more likely that it will not be a problem for Mexican authorities; however, if a DUI felony conviction has been rendered, the situation will be more serious. According to Mexican law, any type of DUI conviction is a felony, but they are aware of the differences in other countries.
(2) The length of time since the DUI occurred: If you have been convicted of drunk driving within the past decade, you can be refused entry into Mexico.
(3) The consequences that were paid: When crossing the border into Mexico, it does matter that all jail terms, probationary periods, and monetary penalties have been completed. Any unresolved issues related to a DUI case could prevent a traveler from being allowed into Mexico.
Lying about a DUI or neglecting to mention it will only make matters worse. It sounds as if you are only on summary probation and have served all of your time and it is doubtful that you will have a problem as long as this is the case and there is no restriction to leaving the country ordered by the Judge. Mexico normally does not do criminal background checks on tourists entering, so again, there should be no problem.
