Cornerstone Aviation has trained hundreds of pilots from all around the world! Some of our students travel from countries such as China, Brazil, India, Iraq, Kenya, England, France, Germany, and South Korea.. Cornerstone has the experience and expertise to ensure that every international student has the resources available to accomplish their individual goal. We can either create a custom training syllabus for an individual student or enroll students in the CSA Traditional Training Program. Students interested in training at Cornerstone Aviation need to hold either a green card or an F-1 Student visa.
