Filling out the forms
You must fill out all sections, unless instructed otherwise. If a section doesn’t apply to you, you must write “Not applicable” or “N/A” in this section. If you need more space for any section, use a blank page to finish answering the question.
If you don’t know a complete date of birth, use “*” (star sign/asterisk) to fill in the spaces for the year, month or day that you don’t know.
If you don’t have a family name on your passport or travel document, enter all given names in the family name field and enter “N/A” or “Not applicable” in the given name field.
If you don’t have a given name on your passport or travel document, enter “N/A” or “Not applicable” in the given name field.
