I'm an F-4, but how do I know if the job I'm doing now is 'simple labor'?

In principle, F-4 applicants cannot work in simple labor occupations listed by the Department of Justice. Some areas designated by the Department of Justice have exceptions based on residence and workplace. The main jobs are parcel delivery and delivery, building and street cleaning, apartment and building security, and parking management. Judgment is based on the actual work you do, not the job title. Just because it's a factory or construction site doesn't automatically mean it's okay or not. Tell us what you actually do, your address, and where you work—and ask 1345.
