Critical Language Scholarship Program
Applicants to the program must be U.S. citizens enrolled in a U.S. degree-granting program at the undergraduate or graduate level at the time of application. Undergraduate students must have completed at least one year of general college course-work by the start date of the program. Other requirements are that the applicants should be in acceptable mental and physical health for which persons granted the scholarship are usually required to submit a satisfactory Medical Information Form and Physician’s Statement. The minimum age is 18 by the beginning of the CLS Program in the particular year.
Driver's licenses in the United States
Driving a school bus also requires a CDL, however the minimum age to drive a school bus is typically higher, usually 25. Some states issue "restricted intrastate commercial driver's licenses", valid for operating commercial vehicles in that state only, to drivers aged 18 and older. Professional drivers who are aged 18–20 typically cannot be licensed to drive tractor trailers, hazardous materials, or school buses.
