Application for a temporary visitor's visa must be made in person. In the case of a minor under eighteen (18) years of age, the application may be made for him by a person who, in the opinion of the consular officer, is responsible for his/her welfare. The minor, not an infant in arms, shall be required to appear at the Consulate for interview, together with the person making the application for him/her.
