No. The US Department of State states that there is no appeal process for a refusal under section 214(b), and the application concerned is completed. Sending a letter or additional documents does not automatically reopen it. An applicant who wants new information or changed circumstances considered must make a new application and pay a new application fee. Questions about account access or a clerical error are separate from an appeal. Always check the section printed on the refusal notice, because instructions for submitting documents after a 221(g) refusal should not be assumed to apply to a 214(b) case.
