Final answer:
As a business owner filling out a passport document, you should list 'Business Owner' or your specific business type as your occupation and 'Self-Employed' or your business's name as your employer.
Step-by-step explanation:
If you are a business owner, when filling out your passport document, for the occupation field, you should indicate 'Business Owner' or the specific nature of your work such as 'Restaurateur', 'Consultant', or 'Retail Owner'. As for the employer section, since you own the business, you can simply state 'Self-Employed', or you can list the name of your business. Choosing what to write depends on what career area or occupation you are in and which industry and job title you identify with. The responses should best reflect your professional identity and the work you do.
