What is the minimum age requirement for a worker to apply for a Blue Card?

The minimum age requirement for a worker to apply for a Blue Card is 18 years old because this age reflects the legal threshold for employment in many jurisdictions, including Hawaii. Being at least 18 years old ensures that the applicant is considered an adult with the legal rights and responsibilities necessary to enter into employment agreements and work independently. This age requirement is also consistent with federal labor laws that regulate the employment of minors, thereby promoting a standard level of maturity and responsibility expected in a workplace setting.
