If I recall, you requested an expedite review based on humanitarian reason(s). And now they’ve asked you to submit applicable documents in support of that request and you’re complaining about them not providing clear guidance as to what could qualify as such. Well, the onus is on you (and not them) to know what you are asking for and to be able to back up the request should the need to do so arise.
An expedite request based on “humanitarian reasons are those related to human welfare. Examples may include, but are not limited to, illness, disability, extreme living conditions, death in the family, or a critical need to travel to obtain medical treatment in a limited amount of time. An emergency may include an urgent need to expedite employment authorization for healthcare workers during a national emergency such as the COVID-19 pandemic. Additionally, an expedite request may be considered under this criterion in instances where a vulnerable person’s safety may be compromised due to a breach of confidentiality if there is a delay in processing the benefit application.
“ So based on this definition, if you believe you qualify for a humanitarian expedite request, provide them with the applicable documentation in support of the request.
