Finish preparatoria or high school and apply for entrance into a university with a legal-degree program. Well-known universities offering legal degrees are The Instituto Technologico de Monterrey, the Universidad Autonoma de Mexico and Universidad Valle de Mexico. Go to the university of your choice in February. This is the month for enrolling in schools. The university will give you the entrance examination dates.
Prepare for the general entrance exam. This exam is based on general information that students should know upon completion of high school. If the entrance test score is high enough, you will be placed on an entrance waiting list. Lists for public universities are much longer than those for private universities. Wait for acceptance. Universities hold lotteries for candidates who have passed the entrance exams.
Complete your undergraduate degree in legal studies, which will take 4 to 5 years (most undergraduate degrees take 5 years to complete in Mexico). The number of semesters needed to complete your degree will be dependent on your passing the coursework and on the semester hours needed for the degree. These are set by the university law program.
Perform your required trabajo social term (internship term). This internship can be completed in the last year of your formal education, as internship positions for Mexican lawyers are usually part time. You cannot graduate unless you have finished all of your course work and your work internship period. This time period is usually 6 months to 1 year, depending on the university and the internship program you have chosen.
Finish your thesis and get it approved and graded to receive your professional legal license. This usually takes approximately a year after you have finished your course work and your internship period.
