When is it acceptable for someone other than the applicant to fill out the application form?

The situation where it is acceptable for someone other than the applicant to fill out the application form occurs when the applicant has illegible handwriting or limited English skills. This is important because the means of communication must be clear and understandable, particularly in formal documentation such as applications. When an applicant struggles with these issues, having another person assist in completing the form ensures that the information is accurately represented. This not only helps in avoiding misinterpretation but also aids in looking out for the applicant's best interests by ensuring that their intent and needs are effectively communicated.
