First, I want to indicate that I completed my studies outside of Colombia (my native country) and upon returning I had to legalize all my documents, so I know how the system is handled.
With a project as sensitive as pre-employment vetting, you need a trustworthy professional who understands the gravity of their work. Being well-versed in both English and Spanish, I can effectively communicate the results for your ease and understanding.
The task at hand requires a seasoned specialist who not only understands the process of verifying educational certificates but also has a grasp on the local education system. As a Colombian, you'll have both - my considerable experience in document verification, specifically with educational qualifications, combined with an added advantage - my familiarity with Colombia's education system.
