The term "native alphabet" refers to the first name, middle name, and last name in non-English characters or the native language of the applicants country of birth. It is a field that appears on the DS-160 form, which is an online visa application form for the United States. The full name in native alphabet field should be filled out in the applicants native language, using any special characters or accents that their name might include. This field needs to be filled out after the surnames and given names fields, and it is not mandatory to fill it out. However, if the applicants name includes non-English alphabets, special characters, or accents, then it is necessary to enter their full name with those characters in the "full name in native alphabet" field. The use of native alphabet in immigration forms is also applicable to other fields, such as the name and address fields, and it is useful when the USCIS needs to send out the form to the persons permanent address. It is not mandatory to fill in the details in the native alphabet in the immigration forms, except for the fields that require the applicants name and address to be in the native alphabet.
